The Dutch side do not get automatic entry into the group stages despite winning the Eredivisie for the 34th time and coming within seconds of reaching the Champions League final.

If they beat PAOK, Erik ten Hag's team will still need to win a play-off to join the likes of Liverpool, Real Madrid and Juventus in the main competition.

It is not the easiest of ties for Ajax who have already lost several players from their exciting young squad.

Central defender Matthijs de Ligt has left for Juventus while midfielder Frenkie de Jong has joined Barcelona.

PAOK went unbeaten on their way to winning the Greek Super League, finishing five points ahead of Olympiakos as they conquered their first league title in over three decades.

The first leg will be played at PAOK's Toumba Stadium on August 6 or 7 with the return in Amsterdam a week later.

Two-time European champions Porto, who finished two points behind champions Benfica in Portugal, will face Krasnodar, who finished third in Russia while Belgian runners-up Club Brugge will meet their Ukrainian counterparts Dynamo Kiev.

If Scottish champions Celtic beat Estonia's Nomme Kalju in the second round of qualifying, they will face either Romanian side Cluj or Maccabi Tel-Aviv of Israel.
