LONDON, February 19- Arsene Wenger has demanded his Arsenal side maintain the standards they set in beating Barcelona when they face League One Leyton Orient in the FA Cup fifth round on Sunday.
Wenger’s side hit new heights against the La Liga champions following a second half comeback that confirmed them to be genuine challengers in the Champions League.
That win, however, came just eleven days after Wenger’s team had squandered a four-goal lead at Newcastle, prompting questions about their consistency and mental strength.
The Gunners manager believes his side can succeed in all four competitions — Premier League, Champions League, FA Cup and the League Cup — but to do so he knows his side must avoid further slip-ups.
It clearly won’t take anything like the level of performance that accounted for Barcelona to win comfortably at the Matchroom Stadium, but the manager has demanded standards are maintained nonetheless.
"We can gain more respect from everybody if we turn up on Sunday with absolutely full commitment then people will say this team is ready to have a real go and not choose the competition or the games," Wenger said.
"When you are a top-level competitive man or team you go absolutely 100 per cent committed into every game.
"The media give more importance to some games than others but for us to win trophies we have to take a distance with that and be able to switch from one competition to another with exactly the same commitment."
Arsenal have failed to win a trophy since their 2005 FA Cup triumph but Wenger remains confident his side is capable of making a clean sweep of silverware this season.
"We want to go for every competition," he said. "I believe we can go in every one to the end but it can also stop very quickly. It’s down to how much we believe and how much commitment we show.
"I’m convinced we have the hunger and we have some talent and we are all committed to go as far as we can."
Wenger’s hopes have been lifted by the news centre back Johan Djourou could be back after recovering from a back injury sustained against Barcelona.
Theo Walcott has also recovered from a hamstring problem and right back Bacary Sagna returns after suspension.
"From the other night we have not lost anybody with a big injury," said Wenger. "Djourou looks to be much better than expected, Walcott as well.
"(Abou) Diaby is suspended so he will not be involved but he could not play anyway, he is not ready."
Orient’s future has thrown into focus in the past week because of the proposal for West Ham to takeover the nearby Olympic Stadium after the 2012 Olympics.
The League One club’s home is located close to the stadium and chairman Barry Hearn has raised fears that the presence of a Premier League team on their doorstep could ultimately kill off the smaller outfit.
Attention will switch back to football this weekend, however, with Russell Slade’s side — who lay tenth going into the latest round of league fixtures — going into the tie on the back of an eleven-game unbeaten run.
Orient centre back Ben Chorley has added incentive to help spring an upset after being released by Wenger in 2003.
"When I was in the youth team at Arsenal we had a lot of success, but I was 21, in the third year of my professional contract and had a chance to go and play for Wimbledon," said Chorley.
"I thought I needed to go and play, and I haven’t looked back. Some 250 games on I finally have the chance to prove to Arsenal that they were wrong."
