A lot has been said by some big names in sports about Cristiano Ronaldo and Lionel Messi on who is the best, with some football managers even weighing in on the debate.
Recently, Liverpool's Jurgen Klopp declared Messi as his pick for the GOAT title, but Sir Alex Ferguson and Zinedine Zidane think otherwise.
But, who else supports Ferguson and Zidane?
Here is a look at five managers who think Ronaldo is the GOAT, with their quotes.
Luiz Felipe Scolari
During an interview in 2017, EFE asked Scolari who would he pick in his dream line-up between Cristiano Ronaldo and Lionel Messi.
The Brazilian replied: “It depends. They have different characteristics.
“Ronaldo has made himself the best in the world. He has trained for it and has dedicated himself to this so he is a different type of player. Messi is all about the simplicity of playing football. He is a pure genius. Ronaldo’s is a situation that he has imposed, but Messi’s is not.”
“I’m Ronaldo over Messi. I love both of them but I’m Ronaldo,” said Redknapp on the Daily Mail.
“There’s him, [Diego] Maradona, Pele, George Best was a genius. I’m a big fan of George Best but you look at Ronaldo, he’s done it on the world stage, he’s won everything, he’s just incredible.”
“Ronaldo’s an incredible professional. They say he’s the last one out of the training ground every day, he trains, I thought Messi would be the same.
“I met two fitness coaches who worked at Barcelona with him, they said he was a nightmare for Pep [Guardiola].
“They said he would come in in the morning, didn’t do a lot of training, he’d kick a couple of balls around and off he went. I couldn’t believe it.”
“Juventus deserve all the credit,” Lippi told Gianluca Di Marzio after Ronaldo joined the Old Lady.
“The team has reached a high level self-esteem to which you could add Cristiano Ronaldo.
“There isn’t anyone else that could increase a team’s yield as much as Cristiano, he’s the best player in the world.”
“I think Cristiano Ronaldo is superior to Lionel Messi, he’s had more goals than matches he played,” said AC Milan boss Pioli, according to CalcioMercato.
Speaking in November 2013 before Ronaldo won the Ballon d’Or, Ancelotti paid his star player the ultimate tribute.
“I’ve seen Ronaldo play a lot of times, of course, but when you’re up close every day his technical skills are unbelievable,” Ancelotti told The Times.
“He’s the best I’ve ever seen. He’s scored in every game in this period — 25 goals in 18 games — and he can score more.”
An astonishing 11 out of the last 12 Ballon d’Or awards have gone one or the other’s way.
So, who is your pick?
