Baku, July 6, AZERTAC Barcelona responded to a trying week by thrashing Villarreal 4-1 away to stay alive in the Liga title race, producing one of their best displays under coach Quique Setien, according to ESPN. The Catalans had drawn their last two matches to hand more momentum to league leaders Real Madrid but Sunday's win took them to 73 points after 34 games, four behind their arch-rivals who won 1-0 at Athletic Bilbao earlier on Sunday.
