Manchester City management are fed-up with the way Raheem Sterling is being treated by refs.

The Sun says City have already complied a dossier of incidents involving Sterling from the past nine months.

They are concerned historic unproven allegations of diving are now counting against the 24-year-old in the eyes of referees.

England winger Sterling was denied a clear penalty by official Andre Marriner when he was wiped out by Terence Kongolo at Huddersfield on Sunday.

But that was the latest in a series of incidents which have left Pep Guardiola and the City hierarchy puzzled and frustrated.

An Etihad insider said: “Obviously you get some, you don't get others.

"But there have been three now in the space of three weeks which replays show to be stonewall penalties.

“It has left some people here scratching their heads. It seems that Raheem is being judged differently to everyone else."
