Wayne Rooney will wear No.10 on his return to Everton - but will Romelu Lukaku take his number at Manchester United?
Rooney completed his return to boyhood club the Toffees on Sunday, 13 years after transferring to United.
The striker wore No.18 during his first spell at Goodison Park - after sensationally coming through the youth system.
He switched to No.8 when we move to United in 2004 before switching to his trade marked 10 after three season at Old Trafford.
Rooney's departure will free up the number for Lukaku at United - with the Belgian set to be unveiled by Jose Mourinho's men immanently.
Lukaku had worn the No.10 on his back for Ronald Koeman's side - having earned it after sporting 17 in his debut campaign.
Rooney revealed he has been wearing Everton pajamas throughout his stint at United.
"To be honest, I've kept it quiet for the last 13 years but I've actually been wearing Everton pyjamas at home with my kids," Rooney said. "I had to keep that a bit quiet!"
