England U21 boss Stuart Pearce believes major changes need to be made to the approach to international tournaments if England are to ever win the World Cup again.
The former England left-back, whose weakened side lost their opening match at the European U21 Championship to Italy on Wednesday, insists the best youngsters should be given more tournament experience early on in their careers.
Pearce said: "I will tell you now what you need to do to win a tournament and be successful.
"It was exactly the same as the French, Spanish and Germans before us. They have all done this prior to us.
"You qualify with your best players. You take your best team to the tournament and you take your best players.
"That is the only way you will have a hope of being successful. The statistics back that up.
"It is whether you want to ignore them and think it doesn't matter, we will just turn up and try to win a World Cup. Or do you want to put the building blocks in place?
"I want them to get that experience (of tournaments) before they step out on to that stage.
"You only have to look at the development of Theo Walcott. He went to the World Cup in 2006. Since then, he could have gone to two World Cups, two European Championships, three Under-21 European Championships, two Under-20 World Cups and an Olympic games, age permitting.
"I think he has only played five-and-a-half tournaments matches in that period.
"We have to address that, so our brighter players, like the Oxlade-Chamberlains, can get tournament experience - playing time - and don't just go to them."
