I feel that we need to get a wide midfielder to be able to replace GIGGS in a few years, and I feel that SWP would be a great addition to the squad. He is young, fast and has proven himself on numerous occassions.
Park, Ronaldo, Richardson, Martin - why do we need another wide midfielder when we got 4 already? Ronaldo is a world class player, Park is excellent, Richardson seems to have stepped up a level and Martin has shown real potential.
Also I don`t think there is any way that Chelsea would sell one of their players to man utd.
