Unai Emery should drop Petr Cech in favour of Bernd Leno for the Europa League final, according to former defender Danny Mills.
Cech, who turned 37 on Monday, confirmed he will retire following the showpiece game between the Gunners and Chelsea in Azerbaijan next week.
A report on Tuesday evening suggested Cech – who joined Chelsea from Rennes in 2004 and went on to win a string of trophies, including four Premier League titles and the 2012 Champions League – was set to take up an off-field role at Stamford Bridge.
“You start to call into question the player’s integrity, his ability to perform,” Mills told talkSPORT.
“And I don’t think that’s in question, but the problem is if he makes a mistake, if something happens in that game.
“Go back to the start of the season where I think they played against Manchester City and he tried to play out from the back and he gave it to some of the Man City players.
“Imagine if he did that again… I just think you’re putting him under enormous pressure, it puts himself under incredible pressure.
“If I was Arsenal, I’m not sure I’d want that. If he makes a mistake, if something happens, there will always be that doubt in people’s minds.”
Mills added: “If I was Arsenal, and they must know what he’s doing and where he’s going at the end of the season, if he is going to go to Chelsea as we believe, I wouldn’t play him.
“He can still walk around the pitch and clap all the fans. But I would not play him in that situation.”
