Real Madrid and Barcelona are on track to meet in the Copa del Rey quarterfinals.

Spain's two biggest clubs breezed through fourth-round encounters against lower league opposition this week using largely second-string line-ups, but will have to dust off their biggest stars should they meet in the last eight.

Today's fifth-round draw pitted reigning champions Madrid against Malaga, while last year's beaten finalists Barca will play Osasuna.
