Arsenal full-back Kieran Gibbs has insisted goalkeeper Lukasz Fabianski has the full support of the team.
The young England defender gave away a penalty late in the Gunners' 3-1 victory over Partizan Belgrade on Tuesday in their UEFA Champions League group game, but the Polish stopper saved Cleo's effort.
It was a much-needed confidence boost for Fabianski, who has previously been lambasted for some poor displays in what has proved to be a problem position for Arsene Wenger's team.
He is battling with Manuel Almunia for the starting jersey against Chelsea on Sunday with his rival, who blundered in the 3-2 home defeat by West Brom, having missed the European game through injury.
Gibbs admitted the whole team were backing Fabianski to justify his potential, and felt that he had proved himself.
"He is a great keeper or else he wouldn't be here at Arsenal," Gibbs said.
"I owe him a lot, although I can't really remember much about (giving away) the penalty.
"He put in a great performance. That is what he is in the team to do.
"Saving the penalty was just as important as scoring a goal for us.
"I think he felt like he had a point to prove. He has shown great character and he doesn't hide away.
"We do feel for him (after the criticism he has had) because we know his quality and he has shown them against Partizan - that is why I think he expressed that after he had saved the penalty and all credit to him."
