Champions League qualifying: Porto & Celtic crash out as Ajax sneak through | OneFootball

Porto and Celtic crashed out in Champions League qualifying but last season's semi-finalists Ajax managed to advance to the play-off round.

It was a day of upsets as giants Porto and Celtic fell in the third round of qualifying following respective losses to Krasnodar and CFR Cluj.

Porto – who had featured in the Champions League group stage in each of the last three campaigns, including a run to last season's quarter-finals – were upstaged 3-2 by visiting Krasnodar on Tuesday.

Krasnodar blitzed Porto with a three-goal first half thanks to Magomed Suleymanov's brace as the Russian side prevailed on away goals after a 3-3 draw.

Scottish champions Celtic were denied a play-off berth by Cluj, whose 4-3 victory on the night in Glasgow secured a shock 5-4 success across two legs.

Celtic led the second leg 3-2 after 76 minutes but Billel Omrani and George Tucudean struck inside the final 10 minutes to silence Parkhead and give the Romanian outfit a memorable victory.

Captain Dusan Tadic was at the double as Erik ten Hag's Ajax held on to beat PAOK 3-2 in Amsterdam, where the Eredivisie holders escaped 5-4 on aggregate.

Tadic scored twice and missed a penalty as Ajax's hopes of repeating last season's remarkable Champions League run stayed alive amid uncertainty over the future of Real Madrid target Donny van de Beek.

In Copenhagen, 22 penalties were taken as Red Star Belgrade sensationally prevailed 7-6 in a dramatic shoot-out.

Penalties were required after the Copenhagen-Red Star tie ended 2-2 on aggregate following Tuesday's 1-1 stalemate at Telia Parken.

Elsewhere, Basel and Dynamo Kiev bowed out as LASK, Club Brugge, Dinamo Zagreb, Olympiacos, APOEL and Rosenborg progressed.
