Manchester United prospect Kai Rooney is still getting around in Manchester City gear.

Back in December Wayne Rooney's eldest son, 11, joined United after initially playing Man City's academy.

The now Derby County manager's wife Coleen shared a snap of Kai holding a puppy - but it was the Manchester City hoodie he had on that caught the eye.

Rio Ferdinand, who played over a decade alongside Rooney for United and England, could not bite his tongue.

He cheekily commented on the Instagram post with: “What's he doing in that top????"
