True. I wanted to write more than one hat-trick but i missed it while preparing dinner and searching for a stream for the Barca game at the same time yesterday.He's the only one who has scored two hat-tricks. Raul, Lucas Perez, Negredo, Morientes, Gerard Lopez and Joseba Llorente have one hat-trick each.
Here's a crazy one: Cristiano Ronaldo has scored four hat-tricks in the knockout stages of the Champions League since he last scored a hat-trick in the group stages (Malmö, 2015). Lionel Messi has scored five hat-tricks in the group stages since the last time he scored a hat-trick in the knockout stages (Leverkusen, 2012).
