Speaking to L'Equipe, Mbappe said: "No, I'm not surprised. I'm his number-one supporter. I've known his qualities since we were 14. I also think he's had a mental breakthrough which means he's more relaxed in front of goal. He's a top player! His room for improvement also depends on what his coach expects of him in this position. I think he's doing very well and he's PSG's main attacking player. Given the form he's in at the moment, he can't set himself any limits, he has to continue like this and he'll finish the year with a lot of wins (laughs)."
