Antonio Valencia's agent believes it is 'very difficult' for the winger to leave Manchester United after he was linked with a move to Juventus.
The Ecuador international joined United from Wigan Athletic in 2009 and was rewarded with a new four-year contract by the Premier League champions in August.
However, the 26-year-old has started only three league games for the Red Devils this season after the summer signing of Ashley Young increased competition in wide areas.
He is reportedly a January target for Juventus, whose Milos Krasic has been linked with a move in the opposite direction, but Valencia's representative Diego Herrera Larrea is not expecting a winter transfer.
"I am aware of rumours of Juventus' interest, but for my part there is nothing concrete," Larrea told calciomercato.com.
"In the past, some Italian clubs were interested in the player but not in recent times.
"I don't think that Juve has spoken with Manchester United because I was not informed, but I cannot exclude it as a possibility.
"I see it as very difficult that he leaves United, first of all because he has recently signed a new four-year deal and because he and his family are very well in Manchester.
"But in football, never say never."
