“Inter came back on the field with a different position than how they ended up in the first half. They seemed more aggressive, a little more 'high', they even tried to attack Barcelona. And then the goal of (Denzel) Dumfries came for 3-2. On high balls the Nerazzurri were that, clearly superior, and this must be a weapon to explore a weapon.
“I will be honest: I expected a little more from Barcelona, especially in the second half. I followed the Blaugrana throughout the season and on other occasions they made more impression on me. This time they were able to conquer interview, the spaces close, suffering when there was suffering with a great spirit of sacrifice.
