People are suggesting that some of the European teams are tired after a long domestic season.
I don't really think so - and you must remember there are lots of reasons why a team does not play well.
You could argue tiredness was the reason behind England's poor performance against Sweden - but it had nothing to do with that and more to do with the way the team was set up.
And it's not as though these are ordinary games - we are talking about World Cup fixtures and players are totally up for it.
Tiredness will probably hit the players when they get back and start the new season.
They won't have had a rest and will have to readjust to life after coming down off the plateaux of playing in the World Cup.
I think you might see a knock-on effect during next season's Premiership season - but not now.
Mental fatigue
It's not even so much the physical aspect of the game - it is the mental side as well.
People sometimes don't realise that professionals play for 10½ solid months a year - it is not as though we can take a week off here and there.
You can get sick of football and players who have not had a break will feel tired.
Not that motivational problems are affecting England at the moment.
England have gone from a team that people would have wanted to play to a team that no-one really wants to come up against.
