Flick spoke about his team's defeat after the game and admitted Barca had been taught a lesson by Atletico. He told reporters: "We didn't play very good in the first half as a team. We had too much distance between everyone. We didn't press how we wanted. In the first 45 minutes or more, we got a lesson. Sometimes it's good in the right moment. Maybe today was the right moment. I am still proud of my team, maybe not today in the first 45 minutes, but across the whole season. When you see how many injuries we have all season, how we adapt...Today was a heavy loss but I am proud of my team. We will come back. We need to start from the beginning [of games]. When you see Atlético players, they had more will, more hunger. And this is what I want from the first minute. We didn't show that in the first half. We have the second leg. We will fight for that. If we are able to win each half 2-0, this is our goal. We need our fans in Camp Nou and we will see what happens."
