He continues in The Observer:
'The problem is you have no chance to check if it is a mistake or not. You cannot play the game again. I kept Reyes and Henry out for the semi-final against Manchester United because I wanted them fresh for the Champions League against Chelsea. You can say it was a mistake but the best chances we had were at the start of the game when they weren't playing. The only realistic thing in football is whether you have won or lost. If you have lost you can say you made mistakes, but consider as well that if you win you can also make mistakes.'
