Manchester United ace Cristiano Ronaldo has revealed ref Rob Styles upset his Mum after booking him for diving against Fulham on Monday.

The Portuguese star was denied his first hat-trick for Manchester United when Styles booked him for diving instead of awarding a penalty.

Ronaldo's double was his 12th brace since joining the Red Devils in 2003 but despite a terrific scoring record, the winger's mother is less than impressed.

Ronaldo revealed: "My mum sometimes says to me 'why do you never score a hat-trick?!'.

"But I always tell her I'm happy to keep scoring two goals.

"I'm a winger, not a striker, but my mentality is always to try and help the team, whether it is by making a goal or scoring one."
