Manuel Almunia has warned of Arsenal's growing strength ahead of this season's run-in.
After a hugely inconsistent start to the campaign, the Gunners now appear to have found their rhythm.
Arsene Wenger's side are back into fourth place, are to face Chelsea in the semi-finals of the FA Cup and meet Villarreal in a UEFA Champions League quarter-final tie.
Arsenal are next in action against Manchester City, the last side to beat them in the league, and Spanish shot-stopper Almunia has rallied his team-mates as they look to continue their fine form.
"People should be optimistic about our form," he said in the Evening Standard.
"We realise how strong we can be and the players are mentally better, more aggressive and everything is improving now as players coming back.
"With eight games left in the league, we are trying to do great things. In the rest of the competitions, we have the same possibilities as the others.
"We will try to bring the supporters good moments because they deserve it."
