Barcelona smashed three past lower league side Real Murcia in the Copa del Rey at Estadio Nueva Condomina to give the Catalan giants first leg advantage.
A much-changed Barcelona side controlled the game before before Paco Alcacer put the visitor ahead on the stroke of half time, looping an excellent header into the net after a cross into the box from the right.
Gerard Deulofeu and teenager Jose Arnaiz extended their lead with a quick fire double in the second half.
A 3-0 deficit seems more unlikely for Murcia to overturn as the return leg will take place at Camp Nou over a month’s time.
Real Murcia XI: Santome, Escribano, Juanra, Orfila, Alex Ortiz, David Mateos, Nadjib, Jordan, Elady, Llorente, Molinero
Barcelona XI: Cillessen, Semedo, Mascherano, Vermaelen, Digne, Alena, Gomes, Denis, Deulofeu, Alcacer, Arnaiz
