Roma defender Rick Karsdorp has been claimed as the alleged player to "betray" his teammates by coach Jose Mourinho.

After their 1-1 draw with Sassuolo, Mourinho accused one of the players of being "unprofessional" and "betraying" him and his teammates.

"I didn't like one of my players and I told him to find another team in January, even if it's difficult," snapped the Portuguese.

Mourinho at the end of the game rebuked the player in front of the whole team. The coach took the staff, the kit men and the squad out of the locker room to speak alone with the players.

Il Corriere dello Sport reports the player involved is Dane Karsdorp.
