Why?
There are eleven different timezones in Russia. England had to travel thousands of miles further than some of their opponents at the last World Cup. Was it used as an excuse even once?
I think Denmark's problem was how hard they were pressing in the first half of games. It certainly looked like they had run themselves into the ground. Don't get me wrong being able to stay at home and having the Wembley crowd is an advantage but it raises an eyebrow how all of a sudden having to travel has become a major issue for some.
