The 2-0 loss, compounded by a second-half strike from Alexander Sorloth, marks a historic night for Atleti, who secured their first win at the Camp Nou since 2006. For Barcelona, history is firmly against them as they have been eliminated from all three previous two-legged Champions League ties in which they lost the first leg at home. However, Flick remains defiant ahead of the return fixture in Madrid.
"We believe in ourselves. In the second half, we did very well with one less player. They also have quality up front. It wasn't easy to defend them, but we had chances to win this game," Flick insisted. The Blaugrana will point to their recent Copa del Rey exploits as proof that they can overturn a deficit against Simeone's men, though they will need a significantly more clinical performance than the one witnessed on Wednesday night.
