USA midfielder Michael Bradley has insisted the team will make it as difficult as possible for England in their Group C World Cup opener on Saturday.
The Borussia Monchengladbach man, who is the son of national team coach Bob, believes his team-mates will demonstrate an aggressive edge that has helped them get to the finals in South Africa.
Speaking to reporters, he said: "We have a way of playing that has got us this far - and we are going to stick to that.
"The most important thing is to go out and give everything we have and make it really hard on England. That means closing them down well. If one guy gets beaten, the next guy is always there.
"It means having a physical edge to the way you play, being committed to running and fighting and covering for each other for 90 minutes. There is a lot of things that go into it.
"When we have the ball, we have to be sharp and put them under pressure a little bit, playing the game in their half and being aggressive with that.
"There are a lot of things that go into it - but having a physical edge is something we bring on our best days and we need that on Saturday."
