According to The Mirror, during the interview, Enrique said: "You must not have seen the game very well, because we changed formation. We moved from a 4-3-3 to a 4-2-3-1, trying to change [things] and above all to move Leo [Messi] inside more, with more freedom.
"We could have stood on our heads today and it would have been the same. I repeat, I'm responsible for this so don't look for anyone else to blame. But I don't like the tone and I would have liked the same treatment all the times we have won that I am getting tonight when we haven't."
After the interview finished, Enrique reportedly walked back up to the journalist and had to be restrained.
Atresmedia reporter Susana Guasch said: "Three people had to hold Luis Enrique back because he was going for Jordi Grau again. [Enrique] was saying 'Don't touch me! Don't touch me!' and said 'Let's see if you use that tone again when we win'."
