The British club are reportedly keen on bolstering their defensive options, with the arrival of a new right-sided defender being a longtime wish of boss Alex Ferguson.
Although Manchester United's number one transfer target was said to be José Bosingwa, Chelsea's quick move for the 25-year-old has made the Scottish veteran turn his attention to the Valencia man.
And Miguel, who has been a first-team choice since moving from Benfica in 2005, has not ruled out a summer transfer despite saying that he is happy with life at Los Che.
Valencia are reportedly going through a financial crisis, and since off-loading some of their main stars seems to be their only option, they should not hinder a lucrative offer for Miguel.
It is understood that a fee of €15 million will be enough to persuade Valencia to allow the Portuguese player, who will be at Euro 2008, to go to Old Trafford.
