I hate to say it, but it's Gerrard IMO. Vidic a close 2nd.
And agreed, I think it'll be beyond ridiculous if Jagielka isn't given a nomination, though I don't expect him to win it or indeed finish 2nd.
Young Player of the Year is a tricky one, namely because there haven't been many who have performed continuously. I guess Agbonlahor for this early-season form, and Bassong should be in there as well. I'd say Rodwell or Gosling, but they haven't really done much to warrant a nomination. Good prospects though.
