Former Arsenal defender Lee Dixon says William Gallas has no future at the club unless he responds positively to being disciplined by Arsene Wenger.
Gallas was stripped of the captaincy and dropped for the Manchester City game after criticising team-mates.
"As manager you want to see a positive reaction and if you don't get one then I can't see him staying," said Dixon.
"Whether he plays for Arsenal again is down to Gallas and no-one else. How does he react?"
Gallas, 31, trained in London on Saturday as the team lost 3-0 at Manchester City, but he could return to the side for Arsenal's Champions League tie at the Emirates against Dynamo Kiev on Tuesday.
Goalkeeper Manuel Almunia took over captaincy duties in his absence but Cesc Fabregas has been touted as a long-term replacement.
Gallas' captaincy has been under scrutiny since Arsenal's match against Birmingham last season where the Frenchman kicked an advertising hoarding and stood in the other half of the pitch as James McFadden scored a last-minute penalty. Wenger said at the start of the season that Gallas was his best choice because he didn't have anybody naturally pushing him for the spot

And in last week's outburst he accused some team-mates of in-fighting, insulting behaviour and lacking bravery.
Dixon, who played for Arsenal for 14 years, said that he has spoken to Wenger about Gallas' leadership before.
And while he accepts that Gallas' comments had an element of truth to them, he maintains the former Chelsea defender was wrong to vent his frustrations publicly.
"I asked Wenger earlier in the season about Gallas being captain because I had been critical of him in the past about how he goes about the role," Dixon said.
"Let's not forget he is an excellent defender and I've not got a problem with that, but I just felt as if he was not helping the team and I asked Wenger about it.
"He said at the start of the season when the issue cropped up that Gallas was his best choice because he didn't have anybody naturally pushing him for the spot.
"He also felt that taking it off him at that stage would not be good for him as a player.
"To be fair what Gallas has said is not a million miles away from the truth, I'm sure that privately Wenger is going 'well I kind of agree with quite a lot of it'.
"The area where Gallas has let himself down is coming out and saying it in the press."
606: DEBATE
He must be shown the door now because he will be even more of a disruption now he has lost the captaincy and he knows that the players went to Wenger to complain about him

Dixon was part of an English core at Arsenal including defenders Tony Adams, Nigel Winterburn, Steve Bould and Martin Keown as well the likes of striker Ian Wright when Wenger arrived as manager in 1996.
But despite questioning the number of experienced players in the current side, Dixon believes that Wenger still values strong leadership in his team.
"One of the things he said when he came into Arsenal was that he loved the mix of English and foreign influence and he liked that English spirit in the dressing room," said Dixon.
"Now he hasn't got that and that's crept up on him but you could say you saw it coming. People say he's anti-English, he's not at all. There are English players in the squad and some young ones coming through but I think the fact that he hasn't got the older English pro in the dressing room is a problem.
"I know he values team spirit and leadership but how it has crept up on him, I'm not too sure. I know him and I know what he likes in his team and to see a team that has not got that is a surprise to me."
