Louis van Gaal will make a return to management five years after his sacking by Manchester United.
The fearsome coach, 69, is to take charge of Dutch second division side SC Telstar next season - but just for the one game.
Van Gaal, who played in Telstar's midfield for a single season in 1977-78, is returning to the dug-out briefly as part of the club's fundraising drive.
Supporters can buy lottery tickets, priced at just £2.50, to be entered into a draw to be Van Gaal's assistant for a one-off fixture next season.
The ex-Ajax, Barcelona, Bayern Munich and Holland boss joked: 'If you want to make a mess of a game alongside me, buy a lottery ticket!'
Other prizes on offer for the draw on July 17 include tickets to the Dutch Grand Prix, PlayStations, football kits and, bizarrely, a shower unit.
A video put out by Telstar showed Van Gaal and his wife Truus walking into Telstar's stadium before putting pen to paper on a new 'contract'.
The money raised from the lottery will be donated to the Spieren door Spieren Foundation, a charity which fights against muscle disease in children.
Van Gaal hasn't returned to management following his two-season spell with United, which culminated in his sacking just two days after they won the FA Cup.
He didn't announce his official retirement from the game until March 2019.
Van Gaal played in the Eredivisie, the Dutch top flight, when at Telstar and then followed their manager Mircea Petescu on to Sparta Rotterdam.
Based in the northern town of Ijmuiden, Telstar are now a second tier outfit and finished 13th in the Eerste Divisie last season. They play their home games at the 3,625-seater Rabobank Ijmond Stadion.
