Ajax finished with 10 men on Tuesday but moved closer to the Champions League group stage with a 0-0 draw away to APOEL in Nicosia in a playoff round first-leg match.
The game was goalless but packed with incident.
Ajax, a four-time winner of the competition and a semifinalist last season, dominated possession and created a string of promising situations.
But the lively home attack, with 22-year-old Jordanian Musa Suleiman showing some eye-catching form, created the most dangerous chances.
Ajax conceded a string of free kicks in the second half and Noussair Mazraoui paid the price when a flailing tackle on Uros Matic earned him a second yellow card with 10 minutes to play.
Veteran striker Klass Jan Huntelaar, who came on with 12 minutes left, had a clear opportunity to win the game in added time, but the 36-year-old’s tame chip was cleared.
“We gave the ball away too easily and we must improve next week,” said Ajax attacker Dusan Tadic. “I expect the same compact defensive zone from APOEL in the second game. But we need to play much better.”
While Ajax were disappointed with an away draw, Nicholas Ioannou, APOEL captain, was happy with his team’s chances.
“We played really well,” he said. “We defended very well and had some good chances at the other end to score. We were quite unlucky not to. We still believe we can go through.”
