Chelsea will reportedly earn a large slice of the transfer fee paid by Wolfsburg to sign Jeffrey Bruma from PSV Eindhoven.
The 24-year-old completed his move to the German outfit on a five-year deal earlier today, following a three-season stint at the Philips Stadion.
Bruma had previously spent six years at Stamford Bridge before departing for PSV in 2013 and, according to De Telegraaf, the Blues inserted a sell-on clause into his contract.
It is claimed that Chelsea could therefore earn roughly 30% of the reported £12m transfer fee - around £3.6m in profit.
While in West London, Bruma spent time on loan at Leicester City and Hamburger SV, being restricted to just four senior appearances for the club.
