Tello has an amazing potential and he shows that he progress quickly ...
But, he still does some mistakes like failing when Messi gives him beautiful balls and he absolutely needs to be more effictive in front of the goal if he wants to continue his progression.
Honestly, I think that he should be titular tomorrow against Paris because their right defender is a real bullshit (Christophe Jallet) and Tello is the kind of player who can unblock a situation by making a call in deepness and by trying to dribble the player who's in front of him and the giving a beautiful ball to Messi or Villa.
Unlike him, Alexis isn't actually confident because you guys know his situation and I just feel that he can't be the solution,rather thanTello.
