With Alexis Sanchez set to take over the iconic No.7 shirt at Old Trafford, Goal looks back at some of those to have worn it down the years...

George Best
An icon on and off the pitch, Best remains the only Northern Irishman to win the Ballon d'Or having finished as United's top scorer for six consecutive seasons before leaving in 1974.

He helped the Red Devils win two league titles as well as the European Cup in 1968, with his goal in the final contributing to a 4-1 victory over Benfica.

Bryan Robson
'Captain Marvel' was voted United's greatest ever player in a poll of their former players back in 2011, and for his all-action midfield displays it was easy to see why.

Playing 461 times for the Red Devils, Robson scored 99 goals and became their first English captain to lift the FA Cup as well as helping to secure Premier League and Cup Winners' Cup triumphs.

Keith Gillespie
Part of the United side that won the FA Youth Cup in 1992, Gillespie followed in his fellow countryman Best's shoes and was handed the No.7 shirt by Sir Alex Ferguson.

He failed to fully establish himself at Old Trafford, however, with Andrei Kanchelskis keeping him out of the team for long periods before he was eventually sold to Newcastle in 1995.

Eric Cantona
When permanent squad numbers were introduced to English football in the 1993-94 season, there was only really one option for United to hand their No.7 to - 'King Eric'.

Signed from Leeds United in 1992, Cantona terrorised opposition defences for five years at Old Trafford, scoring outrageous goals for fun as Ferguson's side began to dominate the English game.

He will likely always be remembered for his infamous kung-fu kick at Selhurst Park, but his playing legacy will never be forgotten on the red side of Manchester.

Glory Glory Man United!
