Barca went behind to Goku Shibasaki's sensational first half strike but Denis Suarez struck in the second half after the hosts failed to clear.
The Barca academy product was given the ball just inside the Getafe box and he took a touch, before firing the ball past a helpless Guaita and into the top corner, a fine strike.
