Chelsea's players are on almost £600,000-a-man to win the Premiership and Champions League Double.
If they pip Manchester United to the Premier League title on Sunday's dramatic final day of the season, the payment schedule drawn up at the start of the season authorises a £2.6m bonus to be shared among the squad.
Some of the players will then earn up to another £369,000 each if they go on to beat United in the Champions League Final in Moscow a fortnight today.
The bonus scheme is operated on a pro-rata basis and means that Joe Cole and Claude Makelele, the only two players to have participated in all Chelsea's 12 Champions League matches this season, stand to make the most money.
Cole will pocket £217,000 if they win the Premier League and a further £369,000 if they lift the European Cup - a total of £586,000.
