Olivier Giroud had a fantastic evening in Spain.
He delivered four goals for Chelsea as the team defeated Sevilla 4-0.
Thus he wrote himself into the history books.
Tonight, Giroud became the first player in Chelsea to score four goals in a Champions League match.
The last time a player scored four goals in a group stage match in CL was when Cristiano Ronaldo scored four goals against Malmö FF in December 2015.
The Frenchman is 34 years and 63 days old, which makes him the oldest player to do a hat trick in the Champions League.
