London, Dec. 23 : Striker Craig Bellamy and coach Roberto Mancini clashed during the latter’s first training session as Manchester City boss.

Mancini reportedly caused an uproar among City stars by insisting on double training sessions and ordering players to stay in a hotel the night before home games.

On Tuesday, he demanded two-and-a-half-hours of hard graft from the entire squad when he took charge of his first workout.

But the Italian was unaware that, because of a recurring knee problem, Bellamy was only expected to do light training.

And after 90 minutes Bellamy "flipped" saying his knee simply could not take it and told Mancini he had to stop.

Bellamy was allowed to walk out of the session along with skipper Kolo Toure, who complained of a back problem.

The pair led a six-player delegation to confront chief executive Garry Cook after Mark Hughes was sacked on Saturday.

The Welsh striker was angry Mancini was not aware of his problems.

Former boss Hughes had put together a special training plan to make sure he could play as many games as possible.

Sun Sport revealed yesterday Bellamy and keeper Shay Given are already considering their City futures.

Bellamy is particularly close to Hughes having played for him with Wales and Blackburn. (ANI)
