Eriksson discovers what thousands of Sunday footballers already knew:
"We have been talking about sleeping, eating, drinking and preparing ourselves as good as possible for the heat. Drinking is extremely important but it does not start one hour before the game. You start the day before the game.
"You have to drink as much as you can and get as much fluid as possible into the body. You can't do that in half an hour. They know it is going to be hot and if you see them, they always have a bottle in their hand before and after training."
