We don't need a striker. If Rooney and Kagawa rotate for the No.10 position then we have Keane, Macheda, Hernandez and Welbeck all fighting for one CF spot. Whether you rate him them or not, Kiko and Keane are part of Ferguson's plans (unless he is lying about Kiko)...
Apart from RB, LB, and CDM, how many left wingers are there? Only Young (forget Giggs and Park, not fast enough). So we could do with a young, pacy left winger like Mcclean.
My summer buys would be: CLYNE, CISSOKHO, MARTINEZ, (KAGAWA) AND MCCLEAN
