The talented youngster has featured 22 times for Valencia this term having broken through into the first team last season.
According to recent reports Manchester United have shown an interest in the left-back, and could even make a move this summer.
However in anticipation of that happening Valencia are said to be preparing a new contract to keep him at the Mestalla for the foreseeable future.
Manchester United are likely to be in the market for a new left-back in the summer, with Patrice Evra likely to be on his way out of Old Trafford.
The Frenchman is on the verge of following Nemanja Vidic to Inter Milan according to reports today.
The Red Devils have previously been linked with Fabio Coentrao from Real Madrid, and Southampton's Luke Shaw.
New Manchester United boss David Moyes has endured a baptism of fire since taking over from Sir Alex Ferguson in May; his side currently sit in 6th in the Premier League while they are 2-0 down in their last 16 Champions League tie against Olympiakos, with the second leg to come next week.
