Jong Ajax
After playing for the Ajax A1 selection for his first two seasons with Ajax, de Bondt joined Ajax reserves' team Jong Ajax for the 2013–14 season. Jong Ajax had recently been promoted from the Beloften Eredivisie, and were now competing in the Dutch Eerste Divisie, the 2nd tier of professional football in the Netherlands. Having been sidelined due to an injury, de Bondt did not make his professional debut until matchday 11, where he substituted in for Boban Lazić in the 74' minute, in the 3–1 away loss to SBV Excelsior in Rotterdam.
