Barca sinks Bilbao, Atletico crashes out

Defending champion Barcelona produced a second-half blitz to come from behind and beat Athletic Bilbao 3-1 to book a place in the King's Cup semifinals after Atletico Madrid crashed out with a 3-2 loss to Celta Vigo.

Inaki Williams put Bilbao ahead after 12 minutes against a lackluster Barca which held a 2-1 lead from the first leg.

The Catalan side woke up in the second half when Luis Suarez knocked in the equalizer. A Gerard Pique header in the 81st minute put Barca ahead and Neymar cracked in a drive in stoppage time.
