Koke scored the only goal of a tight first half as Atletico Madrid took a slender 1-0 lead into the break at Sevilla tonight.
Only three minutes elapsed before Atletico found themselves under pressure, with Jan Oblak pulling off a smart save to keep out Coke's angled effort.
Slowly but surely the visitors developed a foothold, as Antoine Griezmann saw a deflected free kick glide just wide, before Tiago fired straight into the arms of Beto.
Diego Simeone's side continued to look the more dangerous of the two, and Griezmann and Tiago again tried their luck but neither attempt was on target.
Despite Atletico bossing possession, it was the hosts who had the better chances, and another came on 32 minutes when Benoit Tremoulinas was denied by Oblak at the near post.
It proved the biggest moment of the half as Koke swept home Griezmann's ball shortly after to give the visitors a slender lead at the break.
