Danny Welbeck ignited Arsenals title challenge with a last-gasp winner against Leicester on his first appearance in almost a year. Welbeck snatches late win Arsenal breathed life back into their Premier League title charge with a 2-1 victory over Leicester. The substitute rose to flick Mesut Ozils free-kick beyond Kasper Schmeichel in the fifth minute of stoppage time and clinch a 2-1 win for Arsenal at the Emirates Stadium.Earlier, Jamie Vardy had given Leicester the lead from the penalty spot, before Danny Simpsons sending off tipped the contest in Arsenals favour. Theo Walcott dispatched the equaliser in the 70th minute, and the Gunners missed a string of chances before Welbeck finally broke the visitors resolve.Here, we round up the top talking points as Arsene Wengers men moved to within two points of the Premier League summit…Substitutes save Arsenal Welbeck speaks to Sky Sports after his match-winning return from injury In a season of fairytales, Welbeck could hardly have scripted it better. Ten long months had passed since his last appearance in a goalless draw against Jose Mourinhos Chelsea, but desperate times called for desperate measures, and the striker marked his return to the side in the best possible way.Welbecks flicked header from Ozils free-kick was perfectly executed and gave Schmeichel no chance, and he wasnt the only Arsenal substitute to make a decisive impact. Walcotts subdued performances have come under scrutiny in recent weeks, and he had not scored in 10 games when he replaced Francis Coquelin after 61 minutes. Im very happy for Danny Welbeck because I see him every day in training and hes suffered a lot not being able to help the team. Thierry Henry But when Olivier Giroud cushioned Hector Bellerins cross into his path in the 70th minute, the England man produced a composed, side-footed finish for the crucial equalising goal. Wengers substitutions ensured Arsenal ended the game with only one central midfielder on the pitch, but his boldness paid off.Simpson sending-off pivotal Danny Simpson was sent off following a tangle with Olivier Giroud The pivotal moment arrived nine minutes after half-time, when Leicester full-back Simpson was shown his second yellow card for pulling back Giroud. Up until then, the visitors looked good value for their lead, with Claudio Ranieri later saying he felt they would have won had they not gone down to 10 men. Wenger: We were relentless Arsene Wenger hailed his sides relentless energy as Arsenal came from behind to defeat Leicester. The red card certainly changed the flow of the game, with Leicester forced to sacrifice the dangerous Riyad Mahrez for defender Marcin Wasilewski. The substitution immediately reduced their attacking options, allowing Arsenal to apply continuous pressure. Whats more, it was Wasilewski who conceded the late free-kick from which the Gunners got their winner.Gunners undone by Leicester counter-attack Jamie Vardy converts his penalty after Arsenal were caught out on the counter After Manchester City were ripped apart by Leicesters counter-attacks at the Etihad Stadium last weekend, all eyes were on how Arsenal would cope. Wengers plans were disrupted by an injury to Gabriel Paulista, and Leicester took advantage of the Gunners vulnerability just before half-time.The hosts were calling for a foul when Wes Morgan appeared to climb on Mesut Ozil, but Leicester sensed their opportunity as Martin Atkinson waved play on. The exceptional NGolo Kante beat Laurent Koscielny to the loose ball, and Vardy then drew a foul from the isolated Nacho Monreal in Arsenals box. Leicester played like champions Jamie Carragher and Thierry Henry praise the performance of Leicester. It was Leicesters 10th penalty of the Premier League season and the sixth that has been won by Vardy. Giroud attempted to put the Englishman off as he prepared to take it, but his emphatic finished typified Leicesters fearless approach to their title challenge.Kantes midfield masterclass The defeat was particularly harsh on Kante. The midfielder has been one of Leicesters star performers throughout the season, and his man-of-the-match performance at the Emirates came after Wenger revealed Arsenal had passed up on the chance to sign him before he joined Leicester in the summer.Kante constantly disrupted Arsenals build-up play and his touch map showed just how much ground he covered. In total, the midfielder made six tackles, seven interceptions and recovered possession on 13 occasions. He impressed in attacking sense, too. He took up dangerous positions as Leicester poured forward in the first half, and accounted for three of their seven shots on goal.Hes just too much, said Thierry Henry in the Sky Sports studio, and Jamie Carragher was similarly impressed. He has been everywhere, the former defender said at half-time. He has been on the edge of his own box, he has been beating players on the left. He has been amazing.Finishing still a concern for Arsenal Alexis Sanchez heads an early chance over the bar at the Emirates Stadium Arsenal should have been home and dry long before Welbecks winning goal, and their struggles in front of goal remain a cause for concern. The last 20 minutes of the match resembled an attack-versus-defence training drill, but the Gunners spurned chance after chance.In the last 10 minutes alone, Aaron Ramsey, Per Mertesacker, Welbeck and Giroud all missed glorious opportunities. Walcotts 70th-minute equaliser was their first accurate effort of the game, and in total only six of their 24 shots hit the target. With fixtures against Barcelona, Manchester United and Tottenham on the horizon, the Gunners desperately need to rediscover their clinical touch.

Each week, ESPN.com writer Brett Okamoto provides his take on the hottest topics in the world of mixed martial arts.This week, Okamoto squares off with former UFC lightweight champion Anthony Pettis to debate all things MMA ahead of his Saturday showdown against Charles Oliveira at UFC Fight Night in Vancouver, British Columbia. Pettis (18-5) is in a three-fight losing streak for the first time in his career but hopes to stop it against Oliviera.1. UFC president Dana White has said he will not book a trilogy fight between Conor McGregor and Nate Diaz immediately. Is the UFC taking a risk by not doing so?Pettis: The risk is people forgetting about it and not caring anymore. It was a close fight. It could have gone either way. There was a case for either side winning that fight. Im not sure exactly what the UFCs plan is on it. It was a good fight, so Id watch it again. Why not? A trilogy fight would be a hard one to call. They both had some strong points. If Diaz can put some more pressure on him in the second and third round when he gasses, I think Diaz could take it. Conor, I dont think he can finish Nate. If he could he would have early in that fight; he had him wobbled twice.Okamoto: Absolutely not. I know everyone has McGregor/Diaz fever right now, but honestly, I wouldnt even like the idea of cramming this trilogy into one year. Its unnecessary. A third fight will be insanity whenever it happens -- let it sit for now. To me, it can only get bigger. Imagine if one wins a title at lightweight and their final chapter plays out with a belt on the line. And if the worst happens -- both stumble and lose between now and then -- you can still revisit this rivalry. Play the prefight, postfight highlights and well all come back. Zero risk in skipping this trilogy fight for now.2. Whom should McGregor fight next?Pettis: Conor McGregor should be fighting ... I dont know, Jose Aldo is the one with the interim belt. Id like to see that get figured out before he starts moving around different weight classes. Yeah, I would say Jose Aldo. Most definitely a rematch would look different. I think Aldo would not come out as crazy as he did last time, not be as stupid as he was. Conor is one of them guys, though, who definitely has some skills. Hes a big dude to be making 145. Im similar size to him and Im making that cut to 145 now, too.Okamoto: Lightweight champ?Eddie Alvarez. As Ive said before, this entire thing started with a 155-pound championship between McGregor and Rafael dos Anjos. A broken foot, plus McGregors willingness to accept a last-second change in opponent, took us on a serious detour. Im in favor of heading back to the starting line. McGregor can fight very comfortably at lightweight -- hes not killing himself to make weight, nor is he facing guys who are too big for him. Alvarez wants a big name, and as deep as that lightweight division is (and as good as Khabib Nurmagomedov is), theres not a must-see title fight that would prevent McGregor from getting the next title shot.3. If McGregor does not return to featherweight to defend his title, whom should interim champion Jose Aldo fight next?Pettis: I have no idea. I honestly havent even looked that high up. I know he just beat Frankie Edgar, so whoever is behind Edgar. Ive got to go handle business this weekend and then we can start putting my name in the mix.Okamoto: A ranked lightweight. If McGregor says, Eh, Im not interested in featherrweight anymore.dddddddddddd Keep the toy belt, Im heading to lightweight, Aldos response should be, In that case, Im heading to lightweight, too. Lets be real for a minute: McGregor punked Aldo in 2015. Beat him up, verbally, at one press conference after another and then dropped him in 13 seconds. Its on Aldo to get that fight back. McGregor chased him for two years because he was the champion. Now its Aldo who needs to chase. Accept and win fights that force that rematch. Aldo is more than capable of doing that. Hes one of the best fighters in the world. What if Aldo chased McGregor to 155, beat anyone that dared stand in his way and set up that second fight? Can you imagine how big that would be?4. The U.S. Anti-Doping Agency is gathering information on Nate Diazs admitted use of CBD oil at the UFC 202 press conference. Should USADA be investigating this?Pettis: No, I dont think so. Im not really familiar with the rules on how they test for that, but its after the fight. Im pretty sure the amount of THC from that wouldnt be high enough that it would matter. He was kind of pushing the rules, I guess, hes doing it right in front of everybody, but yeah -- I dont know. I dont have a strong opinion on it.Okamoto: The unfortunate answer is yes. And the reason for that is thats what theyre here for. UFC partnered with USADA to establish a strict drug testing environment. Under USADAs rules, what Diaz did is a potential violation -- so for them to just ignore it? They cant. HOWEVER. Any kind of suspension for this would, in my opinion, go against the spirit of the program, which is made to be strict but is not made to bury an athlete who is not seeking any performance-enhancing ability whatsoever. If USADA finds a rule was violated, the punishment should be a public warning and that is it. Rules are rules and Im all for upholding them, but there is also room for common sense to prevail in this program, and I hope that will be the case.5. UFC Fight Night this weekend features a main event between Demian Maia and Carlos Condit. What is more difficult to prepare for: Maias ground game or Condits striking?Pettis: Theyre both dangerous. Ive trained with Carlos; to see the way hes attacking this fight is interesting. I think both of them, you cant catch up to these guys. Condit has years and years of striking experience and Maia, years and years of grappling. Only difference is grappling changes when youre getting punched in the face, so it all depends on how Condit uses his striking to an advantage when it comes to the grappling.Okamoto: Have to say Maias ground game. That doesnt mean I think Maia is better than Condit -- Im just saying, in terms of which strength is most difficult to prepare for ... its Maia. Condits volume is dizzying. Hes outclassed some phenomenal fighters with the angles he creates, the movement, versatility. Its a difficult style to beat. But Maias ground game, you really cant make a mistake. You let Maia into your hips for half a second, hes glued to you the rest of the round. Especially when hes fresh at the start of the fight, Maia will take advantage of any physical or mental pause his opponent takes. Again, doesnt mean Im calling him a better overall welterweight than Condit, but his grappling is one of the most menacing skills this sport has. ' ' '
