The last time Barcelona didn't score was in mid-December, and the club that stopped the scoring machine was Leganes - then at Montjuic (1:0).
The friendly club from the suburbs of Madrid once again kept a great goal against a team that had scored 83 goals in the previous 30 rounds, but capitulated after an own goal by Jorge Saenz in the 48th minute (1:0).
Barça thus continued their path to the title, and now, with a match in hand, are seven points ahead of second-placed Real.
Flick's team had chances tonight through Lamino Jamal and Fermin Lopes, but Leganes was also very dangerous.
In the first half, Borja Jimenez's men were an even more specific rival, and Adria Altimira had a great chance.
Barcelona scored when Saens, in an attempt to intercept Rafinha's pass to Robert Lewandowski, shook his net..
And after that, Leganes had a huge chance, but Diego Garcia shot wide of the goal from an ideal position.
Barça has overcome another obstacle, awaiting responses from Real (at minus seven) and Atletico (minus 10) - the royal club is away to Alaves tomorrow, while the "colchoneros" welcome Valladolid on Monday.
