Gary Neville and Jamie Carragher discuss on MNF who the greatest player of all-time is - Cristiano Ronaldo or Lionel Messi?

Gary Neville and Jamie Carragher disagree on whether Cristiano Ronaldo or Lionel Messi should be seen as the greatest player of all time.

Ronaldo's scoring return to the Premier League has sparked renewed debate about his standing in football history and Neville posed an intriguing question to help provide the answer on Monday Night Football.

"If you were a manager and you could pick any player in history to come off the bench at their peak to win you a game and you only had one substitution left, who would it be?

"It would be Cristiano Ronaldo," said Neville.

"It would absolutely be Cristiano Ronaldo.

"I looked at his goal breakdown. He can score with his left foot, his wrong foot. He can score with his right foot. He can score from distance. He is probably the best poacher now in world football.

"He can score penalties. And if you stick him in the box and hang it up there he will go and score with a header. He might even score with a free-kick.

"So if you think about who is the greatest player of all time, I do think he is the greatest football player who has ever lived. He is the player who could win me a football match in the most different ways. He is the most complete player."

That opinion will doubtless upset fans of Ronaldo's great rival but Neville elaborated on his explanation as to why his former team-mate is ahead of Messi.

"There is no doubt that Messi has scored an obscene amount of goals, he is a ridiculous player," added Neville.

"But Ronaldo, the three big differences are the headers, that Ronaldo has scored four or five times more, the wrong-footed goals, that Ronaldo has scored 30 or 40 per cent more, and he has scored more penalties.

"It just took me to the point where he is more complete.

"The international goals, the Champions League wins, in teams that were not as good as the teams that Messi played in, just takes me to the point where I think he is the greatest player of all time."

Jamie Carragher strongly disagreed.

"You are talking about the different types of goals," Carragher told Monday Night Football.

"It does not matter how a ball goes in the net. It does not matter if one is a header or a free-kick. Messi has a better goal record than Ronaldo.

"Messi is also a playmaker. Messi can run a game. Ronaldo cannot do that. Again, not a criticism. But there is no way in the world he is the greatest player of all time.

"You talk about who you would want coming off the bench. Messi has scored double the amount of goals coming off the bench. It is a ridiculous thing to say. It does not matter if Messi's goals all come with his left foot, the stats prove he has more chance of scoring.

"Two wonderful players. In terms of all the attributes, Ronaldo is a more complete player. He can do things that Messi can't in terms of his weaker foot and in the air.

"But Messi can take you to a place where you can't actually believe what you are seeing. What Ronaldo does is what other players can do, Messi can do things you have never seen before."

Gary Neville takes a close look at Cristiano Ronaldo’s attacking stats throughout his career

At 36, the Ronaldo who has returned to Manchester United is seen as some way past his peak but has he proved against Newcastle, he can still make a big impact.

"This is a different Ronaldo second time around," said Neville.

"We know that he is the most alert, he is the one who anticipates in the box, he is the one most driven to score goals and create great numbers.

"The best way to look at his career and how it has evolved, his involvement in the build-up is limited. If you look at his touches, he goes from 65 touches at Manchester United and it is decreasing year on year.

"He is going from a winger who is involved in the game regularly to someone who is now essentially playing in the penalty box and having a lot fewer touches.

"Again, his dribbles are nearly half what they used to be at Manchester United. He is not going wide, getting on the ball and going past people. That is not saying he will never do it but it has decreased enormously.

"The chances that he creates for others, again, have decreased enormously in the last 10 to 15 years. His assists you can see are getting less. His shots are getting a lot less. His shots from outside the box are decreasing.

"So all these stats are telling you that this is a penalty-box footballer who is restricting his play outside of the box, far greater than at any moment in his career, because of his age.

"But then you look at his stats that are going up, the stats that are improving. Shot conversion has gone from 12 per cent at United to 17 per cent last season at Juventus, his highest ever level, the best of his career.

"His goals, he is at 0.93 goals per 90 minutes last season for Juventus. That has always been high from his third or fourth season at Manchester United.

"It just tells you what Manchester United have signed. This is a number nine. This is no longer the player who will counter-attack from box to box regularly in matches.

Football's Cult Heroes tells the 'Hollywood story' of how a 'misunderstood' Frenchman became Sir Alex Ferguson's talisman and king at Manchester United.

"He will live in and around the box, he will live in and around the centre-backs, he will anticipate, he will make movements that are outstanding across defenders.

"He will hopefully - from Manchester United's point of view - make a big difference in the games where there are narrow margins.

"Manchester United had seven nil-nils last season, the most that they have ever had in Premier League history. They drew 11 games overall and lost six, finishing 12 points behind Manchester City.

"If you are Ole Gunnar Solskjaer thinking about Cristiano Ronaldo, you are looking at stats like that. Is he the man to score a goal in narrow-margin matches. I know it is hypothetical but if they can convert those nil-nils to wins then Manchester United are champions.

"That is the question now. Is Cristiano Ronaldo going to be enough to make Manchester United champions this season?"
