Spain played their opener without a recognised striker, but looked better balanced Thursday with Fernando Torres restored to the first eleven, the centre-forward bagging two great goals in the 4-0 defeat of Ireland.
"The debate about a number nine will continue," Torres told Telecinco television. "This system worked today and worked the other day with Cesc. The good thing is Spain have many players who can fill many positions," he went on.
Del Bosque said for his part: "Torres knows how to find the spaces, it was the perfect match, a lot of people think he could have played in the first match, but that wasn't the point.
"We have a system and we showed it works."
"People think it is important to have a striker and it is important for us as well, but it is more important to win.
