Miguel joined the club in 2005 from Benfica and has done well for the La Liga side ever since. He is a solid right back who likes to get forward a bit, he has made 45 appearances for his home nation of Portugal.
Despite signing a new deal at the club in September, the 27 year old is still being linked with a move away from the Mestalla. It is thought that it will take offers of no less than £8 million for Valencia to even consider it.
Chelsea may be favourites ahead of Villa with the presence of several Portuguese players at the club, but that does not rule the Midlands club out of signing him.
