The 21-year old Dutchman left Craven Cottage to sign a three-year deal with Ajax where he has scored three goals in seven appearances including the go-ahead effort in the weekend's 3-1 win over rivals PSV Eindhoven.
Despite the early success, Jol insists he does not rue the decision to sell Hoesen for a small fee and feels he is better suited to the Dutch style of game than the English Premier League's physicality.
"Of course I have seen the game against PSV. It's nice for the lad he scored," he told Algemeen Dagblad.
"Danny was still too light for the first team. Therefore we let him gain experience at Fortuna.
"The Netherlands is an ideal country for him to develop. Less physical fights, less surviving. Danny really is a decent player. I hope he keeps getting chances at Ajax."
