Cristiano Ronaldo and Manchester United's other iconic No7s ranked by Bryan Robson

Manchester United re-signed five-time Ballon d'Or winner Cristiano Ronaldo from Juventus on the summer transfer deadline day.

Cristiano Ronaldo has a genuine case for being named the greatest player to have ever laced up a pair of boots.

Long-term rival and Argentina icon Lionel Messi would have something to say about that - but there will only ever be one winner when it comes to those with Manchester United connections.

Having scored 118 goals and laid on 69 assists during his first spell at Old Trafford, the returning five-time Ballon d'Or winner touched down in the Premier League for a second act this summer.

Of course, that followed goal and trophy-laden spells with Real Madrid and Italian giants Juventus.

While it was at United where Ronaldo first developed into a global superstar, the Portuguese scaled even greater heights during his nine seasons in Spain - also scoring close to a goal per game during the subsequent years that he spent with Juve.

But where does he rank among a star-studded list of number 7s to have graced Old Trafford?

Eric Cantona, George Best and Class of 92 graduate David Beckham are among those to have shone in that simply iconic United shirt - as well as the man who has moved to put them in order.

During a wide-ranging interview with Mail Online, former United midfielder Bryan Robson shared his views.

Do you agree with Robson's order? Have your say in the comments section below.

Here is how 'Captain Marvel' ranked the contenders - explaining why each of them sit in those positions;

1) Cristiano Ronaldo: "No question."

2) Eric Cantona: "For the huge dramatic impact he brought to the club at a vital moment."

3) George Best: "The magician who sometimes wore 7 instead of 11."

4) Robson: "If I may."

5) Steve Coppell: "A fabulous player before his bad injury."

6) David Beckham: "For his impact on the Manchester, English and global football public."
