Barcelona fought back from 2-0 down to win 3-2 at Sevilla yesterday.
Tito Vilanova's men appeared to be heading for defeat when Piotr Trochowski and Alvaro Negredo fired Sevilla into a deserved 2-0 lead, but Cesc Fabregas' brace pulled Barca level before substitute David Villa secured the win in stoppage time.
Sevilla were not helped by the 72nd-minute dismissal of Gary Medel following a clash with Fabregas, with Barca's final two goals coming while the hosts were attempting to hold on with 10 men.
Barca's sixth win in as many games leaves them four points clear of Malaga at the summit, while Sevilla stay in fifth after their first defeat of the campaign.
