Real Madrid superstar Ronaldo has refused to rule out the possibility of one day returning to Manchester United, according to the Manchester Evening News.

The 29-year-old was linked with a move back to the club he left in 2009 last summer, but ended up signing a new long term deal at Real Madrid.

Ronaldo went on to help his side to Champions League glory last season, but admits ahead of Real’s pre-season clash with United in Michigan, that he hasn’t ruled out the possibility of one day returning to Old Trafford.

Ronaldo said: “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, I love it there.

“I was 18-years-old, I win everything there. The people treat me like a god there so I appreciate it and in the future nobody knows.

“Some players I am still in contact with because when I was there I create a good relationship with everybody, not just the players, all the staff around and it was like my second family there too so I’ll not forget that the people treat me good.

“I’ll not forget, so I appreciate a lot.

“I love Manchester, to be back, I never know, you never know, football you never know.

“I appreciate this club, for me it’s one of the best clubs in the world and I have passion for this club.

“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.”
