Barça began the brave duel, with advanced pressure and with the control of the ball, also of the territory.
But Sevilla is a block, a team that moves the lines to the beat and harmoniously, a defense that is very difficult to overcome.
And it cost Koeman's team his own, only catapulted by Messi's foot and Dembélé's pills down the side.
But they didn't get away with it, nor did a Leo who always had Sevilla as his favorite rival because he had 37 goals in 41 games, already in 42. And that he was able to score when he picked up an assist from Griezmann, also a Bono save, that put the foot out in time before his volley with his left foot.
Without the necessary aim - a slab that Barça has been carrying for a long time - Sevilla took the alternative and did not fail.
It was Koundé, a center-back like the crown of a pine tree that can act as a medium and even a ram.
As in that incorporation in which he dribbled Griezmann and Umtiti - again portrayed - to step on the area and release a whip out of reach of Ter Stegen but within three sticks.
Goal and jauja for Sevilla.
Barcelona tried to put one more march after the intermission and almost succeeded because Bono pulled out a miraculous hand after a tight shot from Messi, also a mitt in time when Dembélé surprised with a corner that pretended to be an Olympic goal.
But the government -prolonged because Messi tried another two shots and a poisoned foul;
Dembélé one more;
and Mingueza one last - it did not translate into a prize and Lopetegui decided to give his team air and oxygen with a triple change (the new left wing and the tip as well).
Enough to maintain the rhythm, to run from area to area and blur a Barcelona that tried but was left with the desire, strangely without changes in the
eleven
until the duel had 10 minutes left.
Koeman's team did not arrive on time, which makes the Cup very complicated. It gives Sevilla so much that they take the lead in the tie.
