Bacary Sagna believes Arsenal can use their latest UEFA Champions League lesson by Barcelona as inspiration to go on and defeat Manchester United as Arsene Wenger's men chase a domestic double, despite the disciplinary fallout from last night's game.
The Gunners were dumped out of Europe at the Camp Nou for the second successive season, where they lost 3-1 - having seen striker Robin van Persie somewhat harshly sent off - as a brace from tormentor-in-chief Lionel Messi helped the Spaniards overturn their first-leg deficit to record a deserved 4-3 aggregate win.
Wenger was left fuming by the decision of Swiss referee Massimo Busacca to show the Dutchman a second yellow card on 56 minutes after he shot on goal following a marginal offside call. Wenger and midfielder Samir Nasri have today been charged by UEFA over comments they made to Busacca.
The Gunners manager and midfielder have been charged with improper conduct for "inappropriate language" towards the Swiss official, with the disciplinary case due to be heard by UEFA on 17 March.
Wenger confronted the referee after the final whistle over the sending off and angry exchanges continued inside the tunnel, with the Gunners manager fuming at the red card which came when the Premier League club had just equalised through an own goal from Sergio Busquets.
The post-match statistics show just what a one-sided affair it was last night, with Barcelona dominating possession while Arsenal failed to muster a single shot on target. Although it has been a difficult couple of weeks for Wenger's side, who suffered a shock Carling Cup final defeat to Birmingham City, all is not yet lost.
Arsenal head to Premier League title rivals United, whom they trail by just three points and hold a game in hand, on Saturday looking to secure a return to Wembley with a place in the FA Cup semi-finals at stake. Right-back Sagna insists having such an important fixture straight after such a disappointment can work in Arsenal's favour.
"We can learn a lot from Barcelona - they kept playing as a team, kept passing the ball quite well. We have to think about the way they played and it must be an inspiration," the France international said. "We have to be strong because we want to be successful. We have to fight for the team, for the fans and everyone.
"We want to bring something back to the Emirates and so we have to think about the next game. Everyone is still confident we can win something. The good point is we don't have time to think about what happened last night. We just want to train as hard as we can and give the maximum."
Sagna feels Arsenal can use their Camp Nou defeat in a positive way when they head to Old Trafford for Saturday's late kick-off. "We are ready to fight because we are even more frustrated after what happened last night and we want to give more," he said. "It will be another big game on Saturday. We just want to go there and play our football."
The performance of teenage midfielder Jack Wilshere over the two legs was certainly a positive for Wenger. Wilshere again showed his huge potential with an impressive display up against the likes of Xavi and Andres Iniesta on a night when captain Cesc Fabregas endured a nightmare return to his boyhood club, with a mistake leading to Barcelona's opening goal for Messi in first-half stoppage time.
The 19-year-old said: "To be playing against people like Xavi and Iniesta is brilliant. It was a great experience. At my age, I am still learning and there are no better players to learn from. Barcelona will probably win it now because they are the best team in Europe."
Wilshere maintains Arsenal cannot feel sorry for themselves. "We have got to pick ourselves up," he said. "We have still got the championship, we are just three points behind and with a game in hand. We will go to Manchester United in the FA Cup on Saturday to get the win." Wilshere added: "We never give up, that is the spirit of Arsenal. We are still in two competitions and need to get a trophy this year, that will be the aim."
