---------De Gea
Rafael Vidic Rio Evra
Cleverly Carrick Anderson
----Rooney Kagawa
------Van Persie
Nani and Young provide backup for Rooney and Kagawa; Hernandez and Welbeck are alternatives to Van Persie. Unfortunately the only role I can think of for Valencia is as backup to Rafael - if we're not playing out and out wingers, his one-footedness becomes an even more serious liability.
Wing play has been our biggest strength over the years. I can't see us completely ignoring that by leaving Valencia and Nani out.
