Erling Haaland is on a 5m bonus as Manchester City chase down the Treble.
The Sun says the striker will earn 1m each if City win the Premier League and Champions League.
He is also on a 350,000 bonus to lift the FA Cup.
Further bonuses are due for goalscoring records and individual awards.
The PFA Player of the Year, Football Writers' Player of the Year and making the PFA Team of the Year will all rake in further cash payments, with Haaland on his way to bank 5m should everything go to plan.
