Spain boss Vicente Del Bosque has confirmed he will rotate his squad for this week's encounters with Czech Republic and Scotland, with La Roja having already confirmed their qualification for Euro 2012.
The World Cup winners have a maximum 18 points from their six qualifiers thus far, and their next two opponents will be vying for second spot in Group I.
But Del Bosque has called on his players to act professionally - with Czech Republic in Prague first up - and ensure they continue their 100 percent record.
"We respect the Czech Republic as they made us work in the last game against them. They have fast midfielders with good technique," he said at a pre-match press conference.
"We have to be good professionals, good sportsmen. The worst thing that could happen would be for us to play without any belief or emotion."
Reports have suggested that Fernando Torres will be rewarded for recent good form with a starting berth on Friday, but Del Bosque would not confirm his starting XI.
"We would love everyone to play in the starting XI because they are all excellent players," he added.
"But there are two games, so I hope everyone in the squad will be able to play at some point."
