I would go for Toure hes played the most games for Arsenal good experience and always gives his all and never in the papers for any bad reasons.

Gallas will be reinstated as captain when he get's back in the team. He will apologise to his teammates and confess to Wenger that he has learned his lesson.

No-one.

Apparantly Arsene doesn't beleve in leadership. Evidenced by recent performances

Gallas will return as captain, but if he didnt it would have to be Toure. Fabregas is a bit young just now to be captain

Nicklas Bendtner would be a popular choice.

Wenger announces that Fabregas will be the new captain. Clicky

I think he's done it to try and get Fabregas to stay.

Watching Arsenal they don't seem to have leaders on the park like your Gerrards, Lampards, Terry so on. Could be a tough on for them.
