Barcelona obtained its place in the final of Copa Del Rey with a 1-0 victory in the second leg against Atletico Madrid which followed a 4-4 wild draw in the first stage.
Hansi Flick is recognized for having certified the victory after proposing a plan for the game, according to Mundo Deportivo.
The German coach predicted that hosts would start with a patient defensive approach and try to hit Barça on the counterattack.
Flick therefore passed the last two training sessions before the game works to accelerate the transitions and do so with the mission of Pedri and Frenkie de Jong for the game.
The Barcelona boss also had to find a way to spend an aggressive low block from Atletico and also used the sessions to focus on the attack with little space.
The winner of Barcelona came from such a movement, Yamal producing an excellent pass to choose Ferran Torres to make home.
Of course, the second half was a slightly different story because Atletico was forced to attack in order to try to stay equal, but Barcelona maintained to obtain a place in the final.
