Haven't seen Pieters play and, whilst its not necessarily a massive indication of his ability, had never even heard of him before our interest. I've seen Cissokho play a fair bit and think he's a great player with a massive future ahead of him. I've mentioned this before but he's very highly-rated and it would be considered a sizeable coup if we managed to sign him.
As its looking more likely that (out of the two) Pieters will join, how good do you reckon he is RKO?
