This fatigue thing may be a bit of a red herring. Don't athletes go to train at altitude to improve endurance. When they return the England squad's lung capacity should be improved so hopefully they have managed to fill them with the airline's recycled "air".
They train at high altitude to prepare for the difficulties o playing at high altitude.
One weeks train isn't going time or them quicker coming back.
It's like saying as running distance improves your fitness and endurance then playing a game after running a marathon will improve your fitness for the game.
