Rayo Vallecano will take a one-goal advantage into the second leg of their Europa Conference League semi-final after a narrow win over Strasbourg at Estadio de Vallecas.
A looping header from Brazilian forward Alemao nine minutes into the second half was enough to hand the La Liga side a slender lead for next week's return leg in France.
Cagey first half lacking quality
Neither side managed to register a shot on target in an opening period short on quality, with Strasbourg dominating possession but failing to test Rayo's goalkeeper.
