David Beckham and Sir Alex Ferguson are set for a reunion in a charity match at Old Trafford.
Sir Alex is due to manage Beckham and a host of other stars to raise funds for UNICEF next month.
For 11 years Beckham was a member of Sir Alex's highly successful Manchester United team. But the pair had an acrimonious split in 2003 after the Scot accidentally kicked a boot that struck the former England captain above his left eye.
Sir Alex sold Beckham to Real Madrid four months after the dressing room incident and then criticised the ex-England captain in his autobiography, but the pair are now on good terms.
The 73-year-old will manage a Great Britain and Ireland XI, which will be captained by Beckham, at Old Trafford on November 14.
It will be the first time the retired Scot has returned to the dugout since calling time on his 26-year reign as United manager in 2013.
Beckham has been a UNICEF ambassador for 10 years,
"I want a world where children can grow up safe from violence, free from poverty and protected from preventable diseases.
In the opposing dugout will be Carlo Ancelotti, who managed Beckham at AC Milan and Paris St Germain.
The Italian will manage a Rest of the World XI led by former Real Madrid and France star Zinedine Zidane.
The other players involved will be announced over the next month.
Tickets are now available on the Manchester United website and are priced from £20 for adults and £10 for children.
