Javier Mascherano has admitted that Barcelona were damaged by internal issues at the start of 2015.
The Catalans were beaten by Real Sociedad in their first game after the winter break and star player Lionel Messi's relationship with head coach Luis Enrique seemed to have broken down after an argument on the training pitch.
However, Barcelona have since managed to turn things around and now sit atop the Liga table once more following their Clasico win over Real Madrid.
