Kinda hard for the players sure, but you can easily just give them a rest.
Simple.
Didn't Wenger do this a while back and people were complaining about him for moaning? -_-
yeah, funny that.
If you read what Kenny said, it's that there's an international, then the opening match of the PL, and then a week off. He's saying why not have the international, and then move the PL game to the week off instead so that players have time to recover from travelling (if over long distances) and the teams have time to prepare properly just before the first league match.
