He's also played in the Champions League. And has done since the age of 16.
I don't know if he's any good or not but comparing him to Crowley or Zelalem is irrelevant anyway.
I'm also certain that no one on here was paying any attention to Tielemans when we were playing Anderlecht. I certainly wasn't.
And even if I was, it's still 2 games against a significantly better team - not exactly the best game to judge a 17 year old.
