Have to seriously disagree with one point there. And you're not the only one to have stated this. Traore is NOT good in the air. People assume because he is tall he is good in the air, when the fact is that he can't jump, can't get any power into headers and can't direct them either.
I must admit on reflection that you are right I remember J.Cole for Chelsea and Canavaro for Juventus also beat him easily in the air
