Real Madrid star Cristiano Ronaldo has refused to rule out the possibility of a move back to Old Trafford.

Ahead of Real’s International Champions Cup meeting with United in Michigan on Saturday, a game the Portugal captain will miss as he continues to recover ahead of the new season – he was coy on whether he could one day ply his trade in the Premier League again.

“Well, of course, it was one of my favourite clubs, Manchester, everyone knows that every time when I speak about Real Madrid I should speak about Manchester United,” Ronaldo told MUTV.

“I loved it there, I was 18 years old, I won everything there.

“The people treat me like a god there, so I appreciate it and [in] the future, nobody knows.

“Of course I’m happy at Real Madrid – it’s my home, it’s my club, but Manchester treat me unbelievable so we never know.”
