Very difficult to assess a player from a handful of games watched on TV. Had seen Koulibally a few times on TV where he looked fantastic and watched more often when we were interested and in those he looked terrible. At 21 he will not be the best left sided centre half yet but may well have the ability to get there and that appears to be the view of Pep and the scouting team. They must be hugely confident they can shape his game to fit our style and he has the ability to develop into the best option for us. Laporte has been absolute quality in the time he has been here and Pep has turned Ake and Akanji into world class players so will go with his choice rather than my guess from a half dozen televised games.Not worried about the price as with advances in cloning we could get 2 for the price of 1.
