In a tightly contested Europa Conference League semi-final first leg, Rayo Vallecano secured a crucial 1-0 victory over Strasbourg at the Estadio de Vallecas, putting them in the driver's seat ahead of next week's return fixture in France.

The match, which saw both teams battle for supremacy in a cagey opening 45 minutes, came alive in the second half thanks to a moment of brilliance from Brazilian forward Alemao. His looping header in the 54th minute—his third European goal of the season—was the difference-maker, converting Isi Palazon's corner at the near post to send the home crowd into a frenzy.

For Rayo Vallecano, making their first-ever appearance in a European competition semi-final, the win is a historic milestone. The La Liga side started the second half with renewed energy, quickly breaking the deadlock after a first half that lacked quality, with neither team registering a shot on target as Strasbourg dominated possession.

Strasbourg, managed by Englishman Gary O'Neil, struggled to regain their early momentum after the goal. The hosts took control, and former Newcastle United defender Florian Lejeune nearly doubled the lead just 10 minutes later, only for goalkeeper Mike Penders to produce a stunning save, clawing his header off the line. Palazon and Unai Lopez also tested the visitors' defense from distance in the closing stages as Rayo pushed for a second goal.

The narrow win sets up an exciting second leg at Stade de la Meinau next Thursday. The winner will face either Crystal Palace or Shakhtar Donetsk in next month's final in Germany, making every moment count for both sides as they chase European glory.
