Manchester City 'have compiled a dossier of incidents where Raheem Sterling has not been awarded a penalty' amid discontent with referees.

The Premier League champions believe Sterling has an unfair reputation for diving and this is counting against the winger when decisions are made.

Sterling was denied a clear penalty by official Andre Marriner when he was taken down by Terence Kongolo during City's 3-0 win at Huddersfield Town on Sunday.

But, according to The Sun, City believe there are at least four other occasions in the past nine months when Sterling should have been awarded a penalty.

The treatment of the 24-year-old England star has reportedly left City manager Pep Guardiola and his coaching team 'puzzled and frustrated'.

A City source told The Sun: 'Obviously you get some, you don't get other.

'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.'

City will now watch closely during their title battle with Liverpool to see if Sterling is denied any other clear penalties.

It came after the club met referees chief Mike Riley last year to raise concerns over a perceived lack of protection for their players by officials.

Sterling has been accused of going down too easily in the past, including by former Arsenal manager Arsene Wenger, who said he 'dives well' after being awarded a spot-kick at the Etihad Stadium in November 2017.
