The giant Spurs striker upset England boss Fabio Capello by not having regulation footwear at the team hotel in Austria.
The Italian insists players follow his strict code, which include wearing trainers. Crouch said: “Mine didn’t arrive the other day because our bags hadn’t got here.
“I had a pair of slippers on and I got pulled up on that. What can I do? I’ve got no trainers.”
Capello’s hard-line approach is in stark contrast to the more lax regimes of previous bosses Steve McClaren and Sven Goran Eriksson, the Swede who took England to the last World Cup.
Crouch added: “It is everything with regards to footwear, and conduct around the hotel. You have to make sure all the rules are abided by. Time-keeping is a main one. The lads seem to arrive 10 or 15 minutes before every meeting!
“It’s going a bit far to say it’s like being back at school. But he’s definitely got that respect and he wants a certain standard. Sven was a lot more laid-back. Everyone was saying that. This time the atmosphere seems a lot more serious, a lot more focused.”
