Arsène Wenger admits he has a job on his hands to lift his players after their Carling Cup heartbreak but he insists they can still finish the season strongly.

Arsenal missed out on the chance to secure their first trophy in six seasons when a late mix-up between Wojciech Szczesny and Laurent Koscielny handed Birmingham a 2-1 victory at Wembley on Sunday.

Wenger and his players were crestfallen after the final whistle but, when the dust settles, they will still be fighting for silverware on three fronts - the Premier League, the Champions League and the FA Cup.

The latter takes centre stage on Wednesday when Leyton Orient visit Emirates Stadium for a Fifth-Round replay and the Arsenal manager will spend the interim rebuilding his squad's confidence.

"Of course [it will be difficult] but that is part of our job, to pick ourselves up," he said. "We have massive challenges in front of us and we do not want to miss them because of this final minute of the game.

"This team has produced a fantastic season until now so we need to support them, try and get behind them and pick them up. Until now they have been fantastic and they have to finish the season as well as possible.

"The disappointment is huge, massive, but we can take a lot of encouragement because the team responded well to being 1-0 down and we had a good performance. It is importance that we take pride from our attitude. Unfortunately we don't bring the trophy home and that hurts a lot."
