Craig Bellamy has been banned from Manchester City and black-listed as one of their players in a show of authority from the club's manager, Roberto Mancini. Bellamy has been told he will not be welcome at City's practice ground when the players resume training tomorrow and ordered to stay away until a deal has been arranged to find him a new club.

It follows several clashes with Mancini and other senior employees over the past few days. Bellamy has been outraged by the way City have marginalised him and has made his feelings clear to the manager and other players. He was told to train with the reserves on Friday but his attitude was perceived to be so "disruptive" the club have told him he is no longer welcome.

An angry Bellamy has returned to Wales to be with his family and is expected to train with Cardiff City tomorrow.

Cardiff have contacted City to ascertain their position and are hoping to capitalise on Bellamy's desire to play for his hometown club by persuading him to take a pay cut on a loan agreement. However, reports of a deal being imminent are premature, with City turning down a request from the Championship club to pay part of Bellamy's £95,000-a-week salary.

City would prefer to sell the 31-year-old but are reluctant to do business with Tottenham Hotspur, confirmed admirers of Bellamy, because they regard Harry Redknapp's team as competitors for the Champions League places. Celtic and Sunderland are interested while Mark Hughes, the former City manager, is trying to sign Bellamy for Fulham plus two more players from his previous club, Roque Santa Cruz and Shay Given.

Several other clubs are understood not to be deterred by the rancorous split and Bellamy's apparent inability to avoid confrontation with authority. Bellamy's CV, including spells at Liverpool, Newcastle United and Blackburn Rovers, has become synonymous with controversy and his eight months under Mancini have been rife with tension and mutual suspicion.

The tone of their relationship was set within Mancini's first weeks as manager when they had an argument about the player wanting an individually tailored training programme.Bellamy was also the subject of an internal investigation into comments in the players' tunnel after Mancini had clashed with David Moyes during the 2-0 home defeat to Everton in March. Someone was overheard shouting something offensive towards Mancini. Bellamy denied it was him and, with noise in the tunnel making it hard to gather evidence, the club decided not to reprimand him.

But Mancini was said to find it "disrespectful and unprofessional" when Bellamy, walking off the pitch after the 1-0 defeat to Tottenham that ended City's hopes of reaching the Champions League, high-fived Redknapp. Then, last week, Bellamy accused Mancini of not speaking to him for six months, an allegation that was strenuously denied. City's directors initially planned to fine Bellamy but instead, on Mancini's recommendation, they have decided to make him persona non grata and effectively wash their hands of him.
