The president of Dutch club Twente has resigned after leaked documents revealed a deal with outside investors for the transfer of players.
Aldo van der Laan said he was leaving because doubts raised by an agreement with Malta-based Doyen Sports Investments were damaging the club.
Twente said the Royal Dutch Football Association (KNVB) was investigating.

The Football Leaks website this week published a contract between Twente and Doyen. The deal was signed in 2014, before FIFA outlawed the practice known as third-party ownership.
Doyen agreed to pay the club €5 million for between 10 and 50 percent of the transfer fee rights for seven players.
FIFA banned third-party ownership as a threat to the integrity of the game because investors forced transfers to make a profit.
