Peter Beardsley is under investigation at Newcastle United, according to a report.
The Mirror claim that Yasin Ben El-Mhanni has accused Beardsley, the club's Under-23 coach, of bullying him.
It adds that El-Mhanni’s complaint, which will be heard at a grievance meeting on Thursday, has been supported by a number of his team-mates.
El-Mhanni is reportedly "deeply unhappy" and felt he had to make a formal complaint to get his complaints heard.
The 22-year-old winger, signed in the summer of 2016, made two FA Cup appearances for Newcastle last season.
Beardsley, one of Newcastle's all-time greats, went into coaching at the club after hanging up his boots.
