You can declare a player useless though.
Bily was useless to us because we needed a winger and he couldn't play there. He was a fine player but was of no use to us because we needed him to play a position he couldn't. Beckford was the same, we needed a lone striker and beckford couldn't play without a partner so he was useless to us while still being a very good player.
If naismith can only play in Fellaini's role than he's of no use to us because we have that position covered, where we want naismith to play is out wide.
why is it covered? fellaini out whos the cover?
this is insanity felli in that role anyway, if we gonna get a big bid for him sure as s*** they won't be playing him behind the striker
