AEK Athens visit Rayo Vallecano in Spain on Thursday for the first leg of their Conference League quarter-final, with a place in the last four on the line and Mainz 05 or Strasbourg waiting in the semi-finals. It is a rare European night for Rayo, who have reached the quarter-finals of the 2025-26 campaign in their first continental run since 2000-01.
Rayo’s last trip this deep into Europe ended in a 4-2 aggregate loss to Alaves in the 2000-01 Europa League, and they have earned this return by finishing fifth in the league phase before edging Samsunspor 3-2 on aggregate in the last 16. They won the first leg 3-1 away and then lost 1-0 at Vallecas, a reminder that the tie is likely to be decided across both legs rather than in one burst.
The Spanish side arrive with a little momentum from domestic football as well, having beaten Elche 1-0 at home in La Liga before the quarter-final first leg. That result moved them up to 13th and left them six points clear of the drop zone. It also ended a run in which they had not won back-to-back home matches since October and November, when they put together three games in a row at Vallecas, including Conference League victories over Shkendija and Lech Poznan.
AEK, by contrast, come into the tie with confidence and altitude. They finished in the top eight in the league phase and then beat Celje 4-0 in Slovenia in the first leg of their last-16 tie before conceding two first-half goals at home and still advancing 4-2 on aggregate. They have not won a European trophy, and they are trying to keep pace in the Greek Super League as well, where Sunday’s 1-0 win over Olympiacos — secured by Aboubakary Koita’s fifth-minute winner — sent them five points clear at the top.
That result stretched AEK’s unbeaten away run to 14 competitive matches, a sequence that includes 10 wins and four draws, and it is the detail Rayo will have to solve first. AEK have already taken away wins over Fiorentina, Samsunspor and Celje in this season’s Conference League, which gives them a travelling pedigree that few teams in the competition can match.
There is also a practical edge to the lineups. Rayo attacker Fran Perez is already out because he was left out of the club’s Conference League squad, while Jozhua Vertrouwd, Abdul Mumin and Randy Nteka are all ineligible. Midfielder Pathe Ciss returns after serving a one-match La Liga ban for an accumulation of yellow cards, giving Rayo one more senior option in a tie that should be tight from the first whistle.
The bigger picture is clear enough. Rayo are back at this level for the first time in nearly a quarter of a century, AEK are hunting both a first European trophy and another step toward their first Greek Super League title since 2022-23, and the winner will move within one round of a final. Thursday’s first leg will not decide everything, but it should say a lot about which club is built to live under pressure when the margins are this small.
