Chelsea are reconsidering Ike Ugbo's loan at Roda JC.
Sky Sports says Chelsea have launched an investigation after learning Ugbo has not been paid while on loan at Dutch side Roda JC.
Ugbo has made a strong impression in the Netherlands, scoring four goals in seven games, but the club has significant debts and currently sit 17th in the Dutch second division.
It is understood the 21-year-old is on a much higher salary than his current team-mates in Holland, and he has not been paid his September wages.
Some reports have suggested the money set aside to pay Ugbo was instead used to pay the rest of the squad.
