MADRID, May 30 (Reuters) - Spain will try out two different attacking formations in Saturday's warm-up match against Peru as they try to settle on a first-choice side for Euro 2008.
'We are going to try out two systems, one in each half,' coach Luis Aragones told reporters on Friday.
Valencia striker David Villa is expected to start up front alongside Fernando Torres in the first half with Aragones trying out a 4-4-2 formation against the South Americans.
But the Spain coach is expected to play a lone front man in the second as he reverts to his favoured 4-1-4-1 line-up.
Aragones said his main worry ahead of next month's tournament in Austria and Switzerland was to ensure all his players were fit and fresh.
'Other sides have preferred to have three warm-up matches, but I've opted for two because the players need some rest, more for psychological reasons than physical ones.... The players aren't at their peak after playing the league, the Champions League and the Cup.'
After the Peru match, Spain will play their final warm-up against the United States in Santander next Wednesday.
They have been drawn alongside defending champions Greece, Russia and Sweden in Group D of Euro 2008.
