Costa has the mental capacity of a 5 year old with attention deficit disorder, I doubt he can even spell 'World Cup year' let alone comprehend its significance. Tell yer what though buy him a big pack of jumbo crayons and he's anyone's.
That would be interesting to say the least...definitely in that diving, cheating, detestable mold like Costa.
He fits exactly what I feel we need in that position (not that I'm entirely convinced that he should be our signing). He's pacey has decent/good technical ability can finish what he is expected to and isn't afraid to move into very wide positions (see DCL) letting people like Rooney, Sigurdsson, Klaassen, and dare I say Barkley move into the space he vacates.
