No-one's doubting his skill level, which is most probably "world class"....but his attitude or lack of it is what's keeping big clubs away from him. I, obviously, don't know the guy but there is plenty of reports about his rather "laid back" attitude. He may be able to change attitude and lack of work rate but few players can change their attitude over night. Spurs have already had 3 French world class talents whose attitude sucked: Dalmat, Taarabt, Ndombele. Ndombele, while at Lyon, run riot when Lyon played Man City in the CL a few years back.
Just a reminder: Here are the highlights of 2 player who were tearing it up in Ligue 1 while at Lyon, but whose attitude sucked...and both were world class talents...
