#2 Serge Gnabry (2019-20)
There was little indication of what was in store when Son Heung-min opened the scoring for home side Tottenham Hotspur. Joshua Kimmich provided an immediate response for the visitors and Robert Lewandowski scored on the cusp of half-time to give Bayern a 2-1 lead, before the Serge Gnabry show unfolded in the second half.
The German winger scored twice to provide a healthy three-goal cushion to Bayern. Although Harry Kane pulled one back for the hosts, any slim hopes of a comeback by Tottenham were doused when Gnabry scored twice more in the last seven minutes. He slotted home either side of a Lewandowski strike, as Bayern condemned Tottenham to their worst-ever home defeat.
In the process, Gnabry provided the Champions League's 15th four-goal hat-trick. It was the 127th instance of a hat-trick in the Champions League, as the German winger became the 93rd different player and the fourth from Germany (also Bernd Hobsch, Uwe Rösler, Mario Gómez and Mesut Özil) to do so.

#3 Cristiano Ronaldo (2015-16)
After Karim Benzema's quickfire double had provided Real Madrid a two-goal cushion inside 24 minutes, Danish visitors Malmo were put to the sword by Cristiano Ronaldo. The Portuguese scored four goals in a devastating 19-minute spell either side of halftime to end the game as a contest.
It was the 100th hat-trick in the competition, and the seventh to be scored by a Real Madrid player (Raúl Gonzalez-1, Ronaldo-1, Karim Benzema-1, Cristiano Ronaldo-4).
The four-goal haul was Ronaldo's first in the Champions League.
