Lionel Messi has become the first player in Champions history to score 6 Champions League hat-tricks, his 36th career hat-trick. The Argentine is also the first player to reach the mark of 50 goals in the UCL group stage.
He achieved this feat today after Barcelona thrashed Celtic 7-0 at the Camp Nou tonight. He is followed closely by Cristiano Ronaldo with 5 hat-tricks in CL.
