Frank Lampard insists England's up and down form during their warm-up programme will have no bearing on how they perform in the World Cup.
Lampard believes England have players such as Wayne Rooney, Joe Cole and Aaron Lennon who will be "able to make things happen" in South Africa during the next month.
The Chelsea midfielder has the games against Mexico and Japan fully in perspective with Fabio Capello experimenting and fielding different line-ups and formations rather than the first-choice team which will face the United States on June 12.
But Lampard admits England have to play to their strengths - at a quick tempo and pressuring their opponents - if they are to do themselves justice in South Africa.
He said: "The Japan match was another warm-up game. Yes, it was not a vintage performance but the second half was much better than the first half, much livelier.
"We played with a lot more intensity and moved the ball quicker. We will take the positives out of it and then look at the negatives and try and put them right for the first game.
"We have to play with our style, which is quick and with pressure, if we are going to do want we want to do in the World Cup and in the second half we got a bit more towards that.
"But these have been two warm-up games and we have been working on a lot of things and training hard. We have not been playing settled teams, people have been tried out and you have got to put everything into the equation.
