Manchester United and Real Madrid are chasing a deal for Umtiti, whose contract carries a €60m buyout clause. And upsetting teammates is Umtiti's reluctance to settle on a new deal - which would include an increase in his escape option.
Pique and Busquets also took Umtiti to task over his attitude towards club staff and some teammates.
"He appears to be only thinking of himself. His attitude has changed in recent weeks," a source stated.
