Mbappe's gesture after the second blunder by Buffon

Paris Saint Germain had nothing to play for in their trip to Reims after having won the title many weeks ago and they did not seem to take the game seriously. 

The home side managed to score two goals and Mbappe could not believe it. Buffon was at fault for both goals and the French youngster made a gesture towards him after the second blunder by the goalkeeper: he raised his hand as if to ask him what he was doing. 

Shortly afterwards, Mbappe, who was trying to get the Golden Shoe off Messi, halved the deficit. Cavani laid off the ball to Mbappe who toe poked it into the back of the net.
