The real problem with Krasic is this... Back with Del Neri he was asked to track back in which he struggled with, this time he struggles to maintain with Conte's movements and tactics as his wingers are one of the most important factors in his system, he relies heavily on his wingers to be more offensive, so tracking back is not the problem. You see Krasic is not that atheltic, he's more technical as he uses his speed and agility to get through his opposition. Basically his predictable straight ball, where he lines up with his marker, kicks the ball and he out runs him, problem is... Thats all he can do, this is Serie A, most teams now either have 3 markers on him... The main issue is, he needs to stop being so predictable, or else... his form will never change.
