All the players in the Manchester United squad will be paid close to half a million pounds each in bonuses if they complete a quadruple.
They have already received around £65,000 for winning the Carabao Cup trophy last Sunday.
Sportsmail reports there will be further bonuses of £85,000 per player for each of the FA Cup and Europa League.
United are in the quarter-finals of the FA Cup and last 16 of the Europa League.
But the biggest bonus would be £250,000 if they somehow overtake Manchester City and Arsenal to win the Premier League title.
That would take the total to £485,000 per player if Ten Hag’s men emerge victorious on all fronts.
