First of all, the guy never said he'd be replacing David and was pointing out that having another fit player in his position will make us less dependent on him.
Secondly, the "gundog fans" are the ones with half a brain who can easily see he's an extremely talented player, even if he's not consistently produced his best form for us so far.
I haven't been on here much this year but it's nice to see some things never change. You don't think he's a decent player? Fine but you're wrong and there's nothing more to it than that.
