Switzerland striker Haris Seferovic has revealed that it will take time for the players to adjust to new manager Vladimir Petkovic.
Long-time boss Ottmar Hitzfeld retired after the Swiss were knocked out of the World Cup by Argentina in the second round and was replaced by the 51-year-old for the Euro 2016 qualifying campaign.
Seferovic told reporters: "There are new rules, for example, we have recently had to wear shoes when eating. He is a different manager with different ideas.
"Mr Petkovic is a very good coach who knows what he wants. But I think we'll need a while to adjust and to play how he wants. But I'm in shape, I feel good.
"When I play, I go into the game the same, no matter what the opponents say. We have respect for England. But we must not have too much respect and play our game."
Petkovic takes charge of his first game later today against England.
