Man United insist Cristiano Ronaldo is STILL not for sale, even as he misses a fourth day of training - and looks likely to miss tomorrow's flight to Thailand - with Chelsea and Napoli upping interest in a £13m deal

Manchester United maintain that Cristiano Ronaldo is not for sale amid growing uncertainty over his future at Old Trafford.

There was speculation on Thursday that United will listen to offers close to the £13million they paid to re-sign Ronaldo from Juventus last summer.

Chelsea owner Todd Boehly is thought to be considering a bid following talks with the player's agent Jorge Mendes, and there is also interest from Napoli.

However, United are sticking to the club's official line that the 37-year-old is not for sale and remains under contract at Old Trafford for another year.
