Mbappe had been criticised following four games without a goal for PSG, and just two in his previous eight matches across all competitions.
But Mbappe responded to his critics with two goals and an assist as Ligue 1 champions PSG eased past 10-man Montpellier in Paris on Friday.
Mbappe is decisive every 58 minutes this season in Ligue 1 (14 goals and six assists) – the best ratio among players involved in more than one goal, per Opta. This is the first time he has been involved in three goals in the same league game (two goals and one assist) since February 2020 (against Dijon).
"I was happy before with his performance because his compromise, but also now that he has scored," PSG head coach Pochettino told reporters.
