Iker Casillas says Spain will not look to use their lack of preparation time as an excuse should they fail to defend their European Championship crown.
As reigning champions, Spain are considered to be the team to beat in Ukraine and Poland.
The 2010 World Cup winners will, however, have little time in which to form squad unity.
Vicente del Bosque will lead his side into international friendly action against Serbia on Saturday unable to call upon the services of a number of key men.
With players from Chelsea, Barcelona and Athletic Bilbao yet to link up with the squad due to club commitments, Spain are unable to name their strongest starting XI.
The absentees are due to meet up with their colleagues in the next few days, but it is already being suggested that Spain's preparations will be adversely affected by their delayed arrival.
Casillas understands the concerns, but the Real Madrid goalkeeper insists the players themselves are confident that they will be ready for tournament competition.
"We'll see if it works against us or not at Euro 2012," he said.
"If Spain don't do well someone will use it as an excuse. It's true, for us, it is a different squad get-together but this is not to say it is worse than previous ones.
"There is no need to dwell on it because all members of the squad have known each other for a long time now."
Del Bosque is due to name his final 23-man squad for Euro 2012 on Sunday.
