Players are 100% fit (usually) before every game, and could play a lot more if they needed to.
And as I said before, there's a difference between what anyone else would call fit, and the extra edge that provides the difference between winning and losing at the top level in any sport. It's not about excuses, it's a fact. Otherwise the same eleven players would be in the team for 90 minutes every match.
What is 100% fit?
It isn't me that's saying it, it's Gerard Houllier.
