Leeds United will receive a payment of around £500,000 after Max Gradel completed his transfer from Saint Etienne to Bournemouth.
United are to profit from a sell-on clause agreed when they sold Gradel to Saint Etienne in 2011.
Gradel’s £2m move - a controversial deal in which Leeds sold their player of the year - guaranteed the Elland Road club 10 per cent of any profit made from a future transfer.
The winger’s switch to Bournemouth - completed earlier today - is believed to have cost the Premier League side £7m.
Gradel has signed a four-year contract at Dean Court, returning to a club where he was twice on loan during the 2007-08 season.
Bournemouth were deducted 10 points by the Football League for entering administration in that campaign and later suffered relegation to League Two.
The turnaround since then has been dramatic and on Saturday Bournemouth host Aston Villa in their first ever Premier League fixture.
“It feels a little bit strange because everything has changed,” Gradel, 27, told Bournemouth’s official website.
“When I first arrived today I didn’t recognise the club, but I am very happy to see it is all moving in a good direction.
“It’s a good feeling. I am so happy. I had a great time here before so I’m very excited to be back.
“Not many people will understand why I came to Bournemouth. I had offers for more money and bigger clubs but in football you have to go where you will be happy.”
