Packed Camp Nou witnessed Barca’s 3-0 landslide win against Sevilla to make an eight-point surplus to their archrival Real Madrid at the top of La Liga. However, all these reasons for celebration and jubilation were put aside, at least for a moment, as one of the most important players in Xavi’s team – Sergio Busquests – limped off the pitch after only ten minutes due to an ankle injury. According to the first reports, the veteran defensive midfielder and Barca’s smooth operator could be sidelined for two or even three weeks.Bearing in mind the fact the Blaugrana are getting closer to their crucial battles on all three fronts (La Liga, Europa League, Spanish Cup), it’s blatantly clear how damaging this Busquets’ injury could be for them.On the other hand, the Catalans did succeed in clinching a vital home win against defence-oriented Sevilla despite some issues in the first half.The visitors were anything but evenly matched with their opponents, yet managing not to concede in the first 60 minutes.
