Butt insists that intense climate conditions and varying stadium infrastructure across different host cities will fundamentally determine whether players can physically sustain a high-tempo pressing style over 90 minutes.
He added: "I don't think you can play like that every game in this tournament, it depends on where you play, the time of kick-off, the heat, if there’s a roof and air conditioning or not. There are lots of different permutations as to how and when you can play high tempo and pressing. If we got to play in Dallas every week, where it is air conditioned, we would have a really good chance. But we're not going to be."
