I think he is still good enough to be a starter in the #10 position as long as he is replaced within 60 mins. Or as sub in any of the attacking midfield roles.Don't get me wrong, I know he ain't good enough now, but some of the abuse is getting nasty and that's just wrong.
It is just he hasn't got the legs anymore to play out wide for more than 30 minutes or the strength to play as a defensive midfielder at all. Sad as I like Ossie, think he is a clever player.
