Personally, I feel a bit sorry for him. I always feel sorry for any professional footballer who'd career is blighted by injury. In the grand scheme of things, they don't get a lot of time "at the top" and for someone like Phil Jones, I suspect when he was around 17/18 etc he would've been dreaming of playing for a top club (hah), playing in World Cups and the like. Really, he's barely played and never showed anything like the promise he once had.
It's a shame, but really his career is over and he will probably end up on a "pay as you play" type contract playing for Everton or Leeds.
