Shocking footage showed Manchester United fans subjecting Jesse Lingard to a torrent of abuse as he boarded the team bus after their 3-0 FA Cup win at Derby.
One United supporter was even stand accused of racially abusing Lingard with at least one Twitter observer claiming they heard the N word shouted in the video.
It is not yet entirely clear if the people involved were all United fans and how many people were hurling abuse towards Lingard.
Lingard's team-mate Luke Shaw appeared by the bus door to furiously remonstrate with the fans after hearing the expletives and insults as they left Pride Park on Thursday evening.
