Atletico had options, but also chances to go ahead in the early stages of the game. This one was characterised by equality, because the Germans did not renounce at all to go for all when they had the opportunity.
But then a problem arose, Gimenez got injured shortly after the game started, around the 13th minute., he asked to be subbed off and threw himself on the ground in rage: It seemed that he was angry that he could no longer continue.
Up until this point, the player was working very hard. Felipe was shining more, but the central pair avoided Leverkusen's most dangerous players. Simeone had to react quickly.
From this point, Hermoso came on, without warming up. He changed his clothese, prepared to come on and was substituted for his team-mate. Maybe he didn't need to move a little earlier because he had the recent, pre-match warm-up, or the coach decided to take him out as soon as possible to avoid shortcomings behind.
