Barcelona’s hopes of winning back-to-back La Liga titles have effectively come to an end in disastrous fashion thanks to a 5-3 loss against Villarreal at the Montjuïc Olympic Stadium on Saturday evening. Barça played an awful first half, dominated most of the second and completed an impressive comeback after going down by two goals, but somehow conceded three times after the 84th minute and were hurt by a couple of awful refereeing decisions en route to an inexplicable defeat that leaves them 10 points behind leaders Real Madrid and ends a difficult week on a sour note.
