The way they achieved it was weirdly disappointing, but Barcelona took another step towards the title.
Barcelona led a two-goal lead slip at El Madrigal against a feisty Villarreal team that just would never quit. It was disappointing for Luis Enrique to see his team collapse from a position in which you could say the Liga was almost wrapped up. But compared to the start of the weekend, Barcelona are in a stronger position than ever, and that's worth talking about.
Forget the particulars of the game and focus on the big picture.
