Manchester United midfielder Bruno Fernandes says Porto's Champions League shock elimination of Juventus is no surprise.

Fernandes has defended Cristiano Ronaldo after he came in for criticism following Juventus' Champions League exit.

"I'm not surprised. Porto he has a winning mentality, he plays aggressive football and I expected him to create problems for Juventus," the Portuguese told La Gazzetta Dello Sport.

“Ronaldo? Cristiano is one of the greats in the history of football. His mentality inspires those who practice this sport. He has won a lot, but no one can win alone.

"I understand that his presence in Juve had created enormous expectations for the Champions League, but when a team loses, they lose an entire squad, not a single player."
