Ronald Koeman's Barcelona started the Dutchman's tenure the best way possible. They were already winning 3-0 in 35 minutes thanks to Ansu Fati's brace and Leo Messi's first goal of the season.
The Barcelona number 10, after a turbulent summer in which he even asked to leave Barcelona and saw how his great friend Luis Suárez did so, scored a controversial penalty.
Ansu Fati won it after a passage of play with Mario Gaspar. The Barcelona player allowed himself to fall in the box despite there seeming little contact.
Ansu Fati, who already had two goals in his locker, gave the ball to Messi. Sergio Asenjo managed to touch the ball but he couldn't stop the shot from the Barcelona forward.
