Nemanja Matic is upsetting AS Roma teammates over claims he wants to join Rennes.
The veteran midfielder, who joined Roma a year ago from Manchester United, is subject of major interest from Rennes.
Il Corriere dello Sport says Rennes have offered him a two-year contract with an option for a third year at 3m a season - and he is tempted.
The fact that he has stopped training with his teammates for a week, officially due to a muscle problem, has senior players suspicious.
Should Matic push through a move away, it will leave teammates disappointed, with the veteran a popular member of the dressing room and regarded as a squad leader.
Further upsetting senior players is that Matic is planning to leave just days away from the new season kickoff.
Roma, meanwhile, are prepared to sell Matic for 7-8m.
