Some Premier League referees are contemplating boycotting Chelsea games in the wake of the allegations made against Mark Clattenburg, according to former official Clive Wilkes.
Police and the Football Association have launched formal investigations into the European champions' allegations Clattenburg used "inappropriate language" towards John Obi Mikel, something Press Association Sport understands the official strenuously denies.
And Wilkes told The Sun: "I keep in touch with a lot of the lads and there is such a strength of feeling about what is happening to Mark. I know a few referees who are even talking about boycotting Chelsea games because of all this."
