Cristiano Ronaldo has now made a sensational return to his former home of Old Trafford, having signed for Manchester United for an initial £13 million (€15m/$18m) fee with add-ons of up to £7m (€8m/$9m).
The striker had informed Juventus coach Max Allegri of his desire to leave Serie A for opportunities elsewhere, and while Manchester City seemed to be the favourites to sign him, it was Man Utd who won the race.
Ronaldo is famed for his relationship with the number seven, but what shirt will he wear at Manchester United? Goal takes a look at the digit that will be on the star's back for the next 12 months and beyond.
What shirt number will Cristiano Ronaldo wear at Man Utd?
Ronaldo has long been synonymous with the number seven, and has even built his entire brand under the 'CR7' name
The number at Manchester United – which Ronaldo has previously worn during his first spell – was previously occupied by Edinson Cavani.
In spite of reports that he was considering an exit, though, the Uruguayan settled on a change of shirt rather than club, and takes 21.
As well as Ronaldo and Cavani, the iconic number has also been worn by United club legends such as David Beckham, George Best, Denis Law, Eric Cantona and Bryan Robson.
What numbers has Cristiano Ronaldo worn before?
Though Ronaldo has built his entire career around his favoured number seven, it wasn't always the number that he was associated with.

He wore the number 28 during his career at Sporting Lisbon, and it was his preferred number when he signed for Man Utd under the management of Six Alex Ferguson in 2004.
It was Ferguson who persuaded Ronaldo to take up the iconic number seven jersey, due to his confidence that the forward could reach the same astronomical heights as previous wearers of the shirt.
Indeed, a new era began at Old Trafford when Ronaldo assumed the number seven shirt, and the rest is history.
Ronaldo did have to initially make do with the number nine shirt when he transferred to Real Madrid in 2009, until the number seven was vacated by club legend Raul, who left for Schalke in 2010.
