Walters can play on the wing, he did that in the FA Cup semi final vs Bolton, was mainly out wide running at the Bolton full backs, but would also drift inside and take on a more central role. There is no reason why he couldnt be in the squad as a back up striker (although I'd start him ahead of Doyle at the moment) and a back up winger for Duff. He also takes a decent penalty so again could be an option to throw on in the 118th min (if he wasnt already on). I think Long could also play on the wing (even if he's better as a striker), so he could say take Walters and Long, plus 4 other strikers.
