Barcelona did enough to win 2-1 at a competitive Leganes on Saturday.
Arturo Vidal scored a scruffy late winner as La Liga leaders Barcelona came from behind to beat bottom club Leganes.
Youssef En-Nesyri's stunning early strike put Leganes ahead while Barcelona toiled in response.
The champions improved after the break and Luis Suarez equalised with a clinical header.
Vidal's finish put the leaders three points clear of rivals Real Madrid, who play Real Sociedad later today.
The Chilean midfielder's goal was fortuitous, Ousmane Dembele's corner deflecting kindly off Ruben Perez and falling to Vidal, who could not miss from a yard out.
Barcelona have lost three times away from home this season.
