The Portuguese superstar famously wore the legendary shirt number during his first spell at United and we can now confirm that Ronaldo will have it on his back once again.
In his first six seasons at the club, between 2003 and 2009, Ronaldo made 292 appearances and scored 118 goals, winning nine trophies including three Premier League titles and the UEFA Champions League.
As we all know, the no. 7 is a special number in the history of United.
It has previously been worn by club icons like George Best, Bryan Robson, Eric Cantona and David Beckham.
