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.Also See:Wenger: We were relentlessLeicester played like championsCustom Houston Texans Jerseys . -- Edmontons Val Sweeting is two wins away from a trip to Winnipeg to play in Canadas Road of the Rings in December.

Running backs Soso Jamabo, Nate Starks and Bolu Olorunfunmi combined for just 92 yards rushing on 28 carries against the Cardinal.Youll still see all three, but you will see less of two and more of one, Mora said.Mora lamented the yards those running backs failed to gain because they misread what was blocked by the offensive line.The game plan was as sound as it could be, Mora said. We left hundreds of yards out there in the run game, and there were some enormous holes that were not hit. I exaggerate when I say hundreds, but probably a hundred in the run game specifically. It was really hard to see it until you looked at the film, and then it was very, very obvious.Offensive coordinator Kennedy Polamalu said after the 22-13 loss that his new duties overseeing the entire offense were limiting how much time he could spend with the running backs during the game. Mora said adjustments have been made, and Kennedy is going to be as involved wwith the running backs as he has ever been going forward.ddddddddddddThe most pressing question for Polamalu will be settling on one feature back. Jamabo started the first two games against Texas A&M and UNLV, while Starks did not play for undisclosed reasons. Jamabo missed the win at BYU while Starks returned, but the team only averaged 1.5 yards per carry. Olorunfunmi has displayed explosiveness as a change-of-pace option, but UCLA has scored one rushing touchdown against the Aggies, Cougars and Stanford.Mora wouldnt assign blame to anyone for those struggles.I dont want to put it on those guys, Mora said. Its everybody. Its always a team proposition. No one player wins or loses a game, or screws up or excels on a play.Add in continued issues with dropped passes in a game where one more touchdown would have been enough to put away Stanford and break an eight-game losing streak in the series, it was hard to put the 24-hour rule into effect.They were as down as I have ever seen this group Saturday after the game. I felt them slowly come back yesterday, Mora said. Well move on with lessons learned.We went out there and competed the best we ever competed against them, center Scott Quessenberry said. It was close. We took it into the fourth quarter. Right down to the last second we had the game won and obviously it was a heartbreaking loss but were not dwelling on it. ' ' '
