Cristiano Ronaldo admits he misses Manchester United but has ruled out an imminent return to the club he left for Real Madrid, the Guardian reports.

Although the forward, who has two years remaining on his contract, has been linked with a move to United and the champions would be keen to re-sign him, Ronaldo says he is happy in Spain.

"I miss English football," he said. "For me, it was [some] of the best years in my career when I was there in Manchester United. Everyone knows that it is a club that is still in my heart and I really, really miss. But now my life is in Spain. I am enjoying playing there, too."

The 28-year-old did not, however, rule out a move back to United. "Part of my life is there, but in the future we never know. I am really, really happy in the Spanish league."

Ronaldo has so far refused to discuss new terms with Real but it would require United to offer £60m for the Spanish club to consider selling a player who has scored 146 goals in 135 appearances for them.
