Chelsea are set to land a percentage of the transfer fee following their former player Jeffrey Bruma's move from PSV Eindhoven to Wolfsburg.
The centre-back recently joined the Bundesliga club for a transfer fee believed to be around £12million after spending three years with the Eredivisie club.
Dutch publication De Telegraaf claims that the West London club will receive around 30%of the transfer fee as part of a sell-on clause.
Wolfsburg director Klaus Allofs confirmed the move: "We are delighted that Jeffrey opted for VfL Wolfsburg.
"He will join us with the confidence of just winning a league title, moreover he knows the Bundesliga from his time at Hamburg and boasts international experience.
"We are convinced he can quickly become an important cornerstone for our squad."
