The former Barcelona and Spain coach has been hammered in the local press since last week's Champions League thrashing at Newcastle.
After yesterday's win, Enrique fulfilled his media duties, which included confronting one of his critics.
The Asturian snapped: "You just go negative, huh? It is scary. All interviews. You are the most negative guy in the history of world football. One day we won 1-4 and he said we deserved to lose.
"Soccer has a lot of circumstances ... young people understand everything, it is you who do not understand it. It's what I think when you ask the questions, but nothing happens."
When the journalist attempted to ease the tension, Enrique left the mic and walked away from the media conference with a smile.
