England have not won the World Cup since 1966 but the future of English football seems bright after victories at the Under-17 and U-20 world championships this year.
The growth in England is a concern for Germany according to former international Bierhoff, who sees similarities in the way the English are developing talent now and the surge made by his home nation after a disastrous showing at Euro 2000.
"Thinking about the England [senior] team from the outside, you are starting to create an air of 'this is a new team' with young players and a lot of characters and by retiring older players who did a lot," Bierhoff said.
"There's a change and I can see you have confidence from the U-20s and U-17s. That shows English football also has developed."
While the former Milan star believes the transition will take a bit of time, he believes that the future is bright for England and that the Three Lions will soon be a major threat on the world stage.
“It’s a good football nation and a strong league," he said. "It’s great to play against them. It takes some time and you see small steps of success in the youth teams. We often see we have successful youth team players who become important in the future.
"Yes we are worried [about England] because the quality of the players will become better."
The 49-year-old pointed to St George's Park as a sign of the advancements England are making.
"I am sure that with St George’s Park, with the investment, coaches and education, that you are catching up," he added.
"It takes some time. We started in 2000 and the first result was in 2010 with new young talented players."
