The Gunners were dumped out of Europe by Barca for the second successive season on Tuesday night after a 3-1 defeat in the Nou Camp. Although it has been a difficult couple of weeks for Arsene Wenger's side, who suffered a shock Carling Cup final defeat to Birmingham, all is not yet lost. They head to Manchester United on Saturday looking to secure a place in the FA Cup semi-finals and Sagna believes 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 Nou Camp 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 Jack Wilshere over the two legs was certainly a positive for Wenger and the 19-year-old enjoyed the experience. "To be playing against people like Xavi and Iniesta is brilliant," he said. "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."
