The father of Ryan Tunnicliffe has won £10,000 after his son made his Manchester United debut in their Capital One Cup victory over Newcastle United.
The 19-year-old midfielder came on as a 77th-minute substitute at Old Trafford, a decade after his dad placed £100 on him to represent the Red Devils first team.
Tunnicliffe has been at the club since 2009, and went on loan to Peterborough United last season, making 26 appearances for Posh.
Sir Alex Ferguson's side have been drawn against Chelsea in the fourth round of the competition.
