Bosingwa has been strongly rumoured with a move to the Premier League, but this is the first time that United have been linked with the Portuguese international. He has also been linked with Boro, Villa and Spurs in past weeks.
United are probably favourites at the moment to secure the Porto number 12's signature because of the Portuguese presence at Old Trafford. It is likely though, that the Superliga side will not let him go for anything less than £8 million.
