[2] Despite rarely playing in his two years for Haarlem, he moved along with coach Hans van Doorneveld to another club in the Eredivisie, Fortuna Sittard, where he would remain the following seven years; during his first ten professional campaigns (one with Fortuna was spent in the second division), he did not miss a single game.

[2] He easily beat competition from Portuguese Vítor Baía,[5] playing in 73 out of 76 possible La Liga matches as Barça won back-to-back leagues (in 1998, the double befell).

[6] In his last season at the Camp Nou, Hesp split first-choice status with youth graduate Francesc Arnau, then moved back to the Netherlands and Fortuna, retiring at almost 37 in 2002.

[8] On 27 June 2024, he moved to the Turkish side Beşiktaş, where he strengthens the staff of coach Giovanni van Bronckhorst.

[9] Although Hesp was picked by the Netherlands for their UEFA Euro 1996 and 1998 FIFA World Cup squads,[10] he never actually won a cap for the national team, acting as understudy to both first-choice Edwin van der Sar and his substitute Ed de Goey.
