Barcelona's Copa del Rey quarter-final with Atletico Madrid remains goalless at the break despite both sides having chances to break the deadlock.

Koke blasted over the bar from the edge of the box on three minutes as the away side enjoyed some early possession, before Neymar's long-range attempt was tipped around the post by Jan Oblak.

Lionel Messi then fired over the top before Neymar collected Jordi Alba's pass and unleashed a shot on goal that was blocked by Diego Godin as Luis Enrique's side took control of the game.

Despite Barcelona's domination, Oblak remained largely untested, and the Madrid side could have snatched an opener when Mario Suarez's shot deflected off Gerard Pique and flew narrowly wide.

With the away side looking dangerous on the break, Fernando Torres could have opened the scoring when he collected Koke's pass following a swift Atleti counter, but the former Chelsea striker saw his effort deflect harmlessly off Pique.

Atletico should have led when Guilherme Siqueira picked out Antoine Griezmann with a cross, but the French forward headed narrowly over the crossbar.

Barcelona's response was immediate as Rakitic's through-ball found Luis Suarez in the area, but he somehow fired over from inside six yards to leave the game goalless at the break.
