Sir Alex Ferguson will attend Manchester United's FA Cup fifth-round clash at Preston North End on Monday, with the League One club stepping up security for the Scot's first trip to Deepdale since his son Darren was sacked.
Former United manager Ferguson will be among those watching on as he witnesses his old club take on the team which axed his son five years ago.
Darren Ferguson left North End bottom of the Championship in December 2010, with his father swiftly recalling three players who were on loan with Preston from United in a move which appeared motivated by revenge.
Ferguson senior later claimed Ritchie De Laet, Josh King and Matty James chose themselves to return to Old Trafford.
Despite retiring as manager of Manchester United, Sir Alex Ferguson still earned £2.17million from the club in a nine month spell from October 2013 to June 2014.
The Scot was paid £100,000 a day in his role as a global ambassador for United, as revealed in the club's accounts, as calculated by the Daily Mail.
Ferguson still has a key role promoting the club around the world.
The accounts also revealed that David Moyes and his backroom staff were paid a collective £4.82million in pay-offs by the club after their contracts were terminated.
Moyes, as well as Steve Round, Phil Neville and Jimmy Lumsden all departed after a poor spell in charge at the club.
Former Germany goalkeeper Oliver Kahn thinks Sir Alex Ferguson has never forgiven him for snubbing the chance to join Manchester United.
Kahn told German fans' website Fanbookz that he had a "serious offer" from the Red Devils in 1994, but he instead opted to join Bayern Munich, with whom he played 14 seasons before retiring in 2008.
"Alex Ferguson has never forgotten that," Kahn said. "He still holds that against me to this day."
According to former United goalkeeper Peter Schmeichel, Kahn committed a cardinal sin.
"You never say no to Sir Alex," the Dane said on the same programme. "It would have been a good experience for Kahn (at United)."

Former Manchester United manager Sir Alex Ferguson has returned to hometown of Glasgow to visit Southern General Hospital in his role as Unicef ambassador.
The retired Manchester United manager met new mother Rebecca Young and her twin boys Elliot and Sandy, along with nurses at the hospital to see how Unicef supports new families.
"As a father and grandfather, I value strong family relationships. Seeing this level of expertise at this hospital emphasises to me how important it is for mothers to have the vital support they need to help nurture their children and give them the best start in life," Sir Alex said.
The 72-year-old also met Kimberley Black, who has spent the last week in the hospital's neonatal unit with her 12-day-old son Jason.
The charity is working with the Glasgow 2014 Commonwealth Games to promote its baby-friendly initiative 'Put Children First', which aims to improve health and reduce disease, poverty and exploitation among children.
