Spain captain Iker Casillas has claimed that his side's 1-0 defeat to England was "not the right result".
Frank Lampard's goal three minutes after the break earned the hosts the win, despite the world and European champions dominating possession.
"It is a shame we didn't manage to win," said the 30-year-old. "It leaves a bitter taste because, in my personal opinion, it was not the right result.
"We created a few more chances than England, who showed their strength at a dead-ball situation and managed to convert something.
"Other than that, I can't really think that they created anything else throughout the game."
Spain will now embark on an 11,000-mile round trip to face Costa Rica in a friendly on Tuesday.
