Ajax endured a tense evening at home against Union Saint-Gilloise but managed to progress despite a 2-1 loss and an early red card.
The Dutch side, reduced to 10 men early in the match, held on to secure a 3-2 aggregate victory after extra time.
Kenneth Taylor delivered the crucial moment just three minutes into extra time, converting a penalty that ultimately sealed Ajax’s passage.
This came after Kevin Mac Allister and Promise Akinpelu had wiped out Ajax’s initial two-goal advantage from the first leg.
Davy Klaassen played a controversial role in Union Saint-Gilloise’s second goal, stopping a goal-bound effort with his arms on the line, leading to his dismissal. David then confidently slotted home the resulting penalty.
However, Taylor’s late winner ensured Ajax’s survival, with his decisive spot-kick awarded following a contentious handball decision.
