Manchester United star Fred has revealed that he has changed his mind on the Cristiano Ronaldo and Lionel Messi debate.

As two of the greatest players to ever grace the sport, Ronaldo and Messi have constantly battled for the "greatest of all time" moniker.

While Fred had a different opinion in the past, he is now backing teammate Ronaldo as being the very best.

"I used to say Messi, it's a style that I enjoy more," he told TNT Sports Brasil.

"But after playing with Cristiano I can see closely the amount of work that he puts into every aspect of his football life.

"On the pitch, he's always in the right place at the right time. He's the player with the highest ability to turn a game around I've ever seen. I choose him now [over Messi].

"He's an exceptional guy, on and off the pitch.

"Every day he's working to get even better and that's important as an inspiration to all of us, especially the young players. He's a role model."
