BARCELONA suffered another humiliating loss as they were humbled 1-0 by minnows Vallecano.
Barcelona named a strong starting XI including summer arrival Sergio Aguero.

Vallecano took their chance in the 30th minute when Falcao fired home a clever finish.
And Barca’s woes continued as Depay, another summer arrival, missed a second-half penalty to level the scores.
