I think a lot of our creativity is pinned on Huddlestone because he can pass the ball so well, but he's not actually THAT creative. For me his perfect role is that of a "defensive" midfielder, who sits infront of the back 4 and controls the game from deep.
Because of his lack of mobility, he wont be that affective further forward.. If you look at best attacking midfielders, they're always the small, agile type, Tom is not that player.
Next season if we're still in the prem id love to see us buy a proper attacking midfielder, like your silva's, nasri, kagawa's etc.. obviously not as good and much cheaper.. but you know what i mean. Someone who can be creative and take a man on further up the pitch. Then I feel we'll see the best out of huddlestone, when he can relax a bit more and doesnt have the whole stadium's hopes pinned on his shoulders.
