 He earned a reputation as a tough tackler, and his performances did not go unnoticed by Eredivisie clubs, as he joined PSV Eindhoven in the summer of 1989.At Eindhoven, de Jong's career never really picked up due to the stiff competition for a starting line-up berth, and after having played only 51 games in five years, which included a short loan spell at FC Groningen, he was eventually released.However, during his time at PSV, he was capped three times for the Netherlands, making his debut on 21 November 1990 against Greece in a UEFA Euro 1992 qualifying match; his last international was on 17 April 1991 against Finland, for the same competition.
