Cristiano Ronaldo suggested Juventus brought him to the club "to help do things they have never done before" after his hat-trick heroics sent them to the Champions League last eight.

Ronaldo's treble brought Juventus back from a 2-0 aggregate deficitagainst Atletico Madrid on Tuesday night in Turin, going through 3-2 on aggregate.

Five-time Champions League winner Ronaldo has scored eight hat-tricks in the competition, the joint-most in the competition alongside Lionel Messi, and the Portuguese forward suggested his big-game impact is why Juventus brought him to the club from Real Madrid in the summer, with the Italians looking for a first European Cup crown since 1996.

"This was why Juventus brought me here, to help do things that they have never done before," said Ronaldo, now 34. "This is the mentality you need to win in the Champions League.

"I just do my work and I'm very happy tonight, it was a magical night. Atletico are always difficult to face, but we are also strong and we proved it.
