The agent of Rick Karsdorp is demanding an explanation from Roma coach Jose Mourinho amid claims he told the Dutchman to leave the club after their 1-1 draw with Sassuolo.

Mourinho accused one of his players of 'betrayal' after the midweek clash, with Italian media sources claiming it was Kardorp who was the subject of his ire.

“I am surprised by Mourinho's comments," Karsdorp's agent Johan Henkes told NOS.

“We want an explanation. We are stunned also that everyone is pointing the finger at Rick, without Mourinho or Roma saying his name.

“We demand an explanation from the club on what the coach said and the way in which he did it. This is not the way you treat a player who has been at Roma for five years."
