Hansi Flick really did a big mistake to play Ferran Torres first, it could have been Robert Lewandowski then substitute him and bring Ferran Torres in the second half though i don't see the development being a major challenge that Barcelona have, they should just be careful of Julian Alvarez and Antoine Greizmann so that they don't score more goals.
Relax, the coach has everything under control, Ferran Torres is doing just fine as a starter, although the goal he would have scored was cleared off the line by an Atletico Madrid defender. It took Barca 2 minutes to equalise the 2 goals defecit. Right now, Barcelona is all over Atletico Madrid and they look like a team that will or may likely win this game. I feel they will win this because, the Copa Del Rey is Barca main competition that's why they have won it the most.
