Spain claimed their biggest ever World Cup win and took pole position in Group E in a comfortable 7-0 victory over Costa Rica on Wednesday.

Dani Olmo opened the scoring with a neat turn and finish on 11 minutes to hand Spain an early lead at the Al Thumama Stadium in Qatar, and Marco Asensio doubled their advantage 10 minutes later with a well-taken finish from a Jordi Alba cross.

Costa Rice provided little in response, and their task became harder on 31 minutes when Alba was brought down by defender Oscar Duarte in the box, with Ferran Torres converting the ensuing penalty.

Torres added his second on 54 minutes when he took advantage of some sloppy Costa Rica defending before Gavi added another with a superb volley, becoming the youngest World Cup scorer since Pele in 1954. Striker Carlos Soler came off the bench and netted Spain's sixth on 90 minutes, while fellow substitute Alvaro Morata scored a seventh moments later.

Spain, who last won the World Cup in 2010, face Germany on Sunday -- a now pivotal game for Germany who suffered a shock defeat to Japan earlier on Wednesday.

"We're happy. We knew it would be a difficult game. It's true that at half-time we already had a big lead but in a competition like this the goals can be useful, so we went for more," Torres told Spanish TV station TVE.

"Now we'll think about Germany, watch videos of how they play, and we're excited to play. I don't know if we're candidates [to win the World Cup] but we have an extraordinary group, we'll make things difficult, and we want to do big things.

 Spain boss Luis Enrique told TVE. "Praise weakens you and we won't fall for that. Our idea is to always play the same way, of course we won't win the rest of the games scoring so many goals, but we're a difficult opponent, anyone who understands football can see that."
