Zidane was never playing out wide in the PL so the comparison is a bit off. I really don't think Kulusevski will do particularly well long term if we have him out wide. He simply doesn't have the burst of pace that successful PL wingers possess currently. Even a player like Sancho (technically excellent, very intelligent player) has struggled with not really having that speed to consistently beat his marker 1v1, it's a big deal in England. And he's a better player than Kulusevski.
Centrally though it's not a problem, and that's where I expect him to end up. We're a bit short on competent wide players so I'm sure he'll play wide for now, but I do see him going central in his career if he wants to make the best of it.
