"But his career has also been blighted by controversy and he ended the season out of favour at City after an alleged training ground assault on team-mate Ousmane Dabo.
After the Dabo incident in May, City suspended Barton, with the midfielder missing the club's last two games of the season.
Greater Manchester Police questioned Barton on suspicion of assault following Dabo's claims he was attacked during a training session at City's Carrington training ground on 1 May.
A police spokesman said Barton had been bailed until 11 July pending further inquiries.
In 2004, Barton was fined a club record six weeks' wages after stubbing out a cigar in team-mate Jamie Tandy's eye during City's Christmas party.
Barton ended up in more trouble during City's pre-season tour of Thailand in 2005, when he physically attacked a schoolboy Everton fan and had to be restrained by team-mate Richard Dunne.
Barton was subsequently sent home in disgrace and fined eight weeks' wages."
