Steven Bergwijn reportedly sacrificed a £6m bonus from former club PSV Eindhoven in order to secure his move to Tottenham Hotspur last month.
The 22-year-old joined Tottenham in a £27m deal on Wednesday, ending a nine-year stay at PSV having come through the ranks with the Dutch outfit.
The Mirror reports that Bergwijn would have been due a bumper £6m bonus had he stayed with the club until the summer, but he instead decided to forego that money in order to seal his switch to North London in January.
PSV sporting director John de Jong is quoted as saying: "Steven has given up a percentage of the fee in order to let the transfer take place."
Bergwijn made 149 appearances for the PSV senior team during his time at the club, scoring 31 goals including a season-best of 15 last term.
The Netherlands international helped PSV to three Eredivisie titles but left in acrimonious circumstances following unconfirmed reports that he went on strike to force an exit.
