After conquering the world at Under 20 level and reaching the semi-finals
 of the Under 21 European Championships, England can afford to dream
 a little this summer. 
The success of the FA's youth teams is reason for good cheer among 
England fans. Some may even be daring to predict the next golden 
generation, of a tournament-winning side about to bloom. 
Yet, if England's youngsters are to truly establish themselves as a
 force in international football, they will have to prove themselves 
against the best.

On Tuesday night, they have a chance to do so, as the U21s take 
on Germany in their European Championship semi-final. Victory would
 be a statement indeed. 
For what better country to measure oneself against than Germany, 
the nation where fresh footballing talent slides off the conveyor belt as
 frequently and seamlessly as BMWs, Volkswagens and Audis do. 

Back in 2009, Germany won this tournament with a team made up
 of familiar names. Mesut Ozil, Manuel Neuer and Co. would go on to
 form the nucleus of the team which won the World Cup in 2014.
This was not just one golden generation. The conveyor belt kept running, 
and every year, Germany's clubs churn out more and more young stars. 
Many, such as Julian Draxler, Emre Can and Antonio Rudiger, had barely
 passed adolescence by the time they established themselves at top 
European clubs.

'We have a lot of talented players in our Bundesliga clubs,' said 
Germany head coach Joachim Low earlier this month. 
'But the level we are aiming for with our young players is not just the
 Bundesliga. The bar we have set ourselves is at the world class level, 
the level of Messi and Ronaldo.' 
Low's demand for his young players is not just a pipe dream, 
but an ongoing project. Draxler, at 23, is the most experienced player 
in the senior team squad which Low has taken to the Confederations
 Cup in Russia this summer. There, he is playing alongside the likes
 of Joshua Kimmich, Leon Goretzka and Timo Werner, all also in their
 early twenties. 
Having taken their best youngsters to Russia, one might expect 
Germany's U21 team to be a little short on talent. Nothing of the sort.

Among the players England will face tomorrow, Mahmoud Dahoud
 has signed for Borussia Dortmund this summer, Serge Gnabry
 for Bayern Munich. Max Meyer made his Champions League
 debut four years ago, while Davie Selke came second in the 
Bundesliga with RB Leipzig last season. Meyer, Gnabry, 
Maximilian Arnold and Yannick Gerhardt have all already been 
capped for Germany's senior team.
The unstoppable wave of talent is largely a result of reforms which
 the German FA (DFB) implemented at the turn of the millennium, 
as German football reached its lowest ebb. 
Among other things, the reforms obliged all first and second division
 clubs to establish a dedicated youth development academy. With clubs 
lower down the tree also getting on board, Germany football's grassroots
 were revolutionised all over the country. 
Unlike France's Clarefontaine and England's St. George's Park,
 the new youth development programme in Germany was not based
around a central development centre. With clubs all over the country
 providing uniform, state of the art youth academies, the idea was that
 the best talent in every region of Germany would have a high class
 academy within a stone's throw of their home.

In a federal country where various societal and political structures
 can differ from area to area, the DFB's model is designed to 
fit seamlessly into society at large, rather than simply trying to create
 footballing genius in a vacuum. And the drive to discover new, local 
talent is relentless. 
At RB Leipzig, they hold regular trial days open to young players
 from local clubs. The best may earn a place in the RB academy, 
where youth players train on a pitch adjacent to the first team. 
All the academies are subject to a rigorous and regular review
process from the DFB, which not only establishes whether the 
academies are good enough to earn a league licence, but also
 certifies them with different grades.

GERMANY UNDER 21S - FIVE TO WATCH 

Sportsmail has picked out five names to look out for in the current Germany Under 21 squad.
Serge Gnabry
After struggling for several years at Arsenal, Serge Gnabry lead Germany's Olympic team to a silver medal finish in Rio last summer, before being a key player in Werder Bremen's remarkable transformation last season. 
His form has earned him a move to Bayern Munich, where he hopes to challenge Arjen Robben and Franck Ribery for a place on the wings. 
 
Yannick Gerhardt 
A left back who can also play in midfield, Yannick Gerhardt was one of several homegrown players to develop quietly at Köln over the last few years, making 74 appearances for the club and earning a call-up to the national team. Though his €13m move to Wolfsburg proved to be an error of judgement in terms of team success, Gerhardt still has a bright career ahead of him at 23. 
 
Mahmoud Dahoud
With two seasons of Champions League football behind him, Syrian-German midfielder Mo Dahoud is one of Germany's most famous and experienced 21-year-olds. After an explosive first season at Borussia Monchengladbach, he dropped off a little last term. 
His quality, though, is undoubtable, and has earned him a move to Dortmund this summer. Penetrative going forward and full of fight in defence, Dahoud is an invaluable defensive midfielder, well-suited to teams who are quick on the break. 
 
Maximilian Philipp
Though he has found himself behind Mitchell Weiser in the pecking order at this tournament, Maximilian Philipp is considered to be one of Germany's most exciting young attacking midfielders. Brilliant on the wing for Freiburg last season despite regular injuries, his 9 goals in 25 appearances earned him a €20m move to Dortmund this summer. 
 
Max Meyer 
Though he has never quite lived up to the expectations that were heaped on his teenage shoulders when he emerged at Schalke half a decade ago, Max Meyer remains an undisputedly gifted midfielder. 
The stocky youngster still needs a little more breathing space to develop his real potential, but he has assumed a leadership role at this tournament, directing play from attacking midfield.Each centre is also obliged to apply key areas of emphasis, set out by the DFB. These include the 'cultivation of a specific and stable level of fitness', 'systematic performance development based on intensive performance analysis' and 'formation of teams on the basis of a future-oriented tactical approach'. 
(The Mail, UK)
Though the DFB visited Clarefontaine on a fact-finding back in 2008, plans for a centralised academy in Frankfurt have hit rocky ground on legal and financial issues in recent years. 
Yet with the clubs still providing the motor of the country's talent factory, that has not stopped the flow of upcoming talent. 
Some clubs are more prolific than others. Seven of Germany's U21 squad came through the ranks at VfB Stuttgart initially, with the likes of Kimmich, Selke and Gnabry going on to play for Bayern, Leipzig and Arsenal. 
It is against those players, with a wealth of experience at the highest level of club football, which England's finest must measure themselves on Tuesday evening. 
Germany's U21 talents are not simply raw diamonds. By their early 20's, they are well-oiled machines, products of a system which allows them to develop individual talent while also rigorously schooled in a comprehensive and uniform approach to team play. 
Yet some still see problems. In a country which used to produce fearsome leaders such as Stefan Effenberg, Oliver Kahn and Lothar Matthaus, some in Germany are concerned that the systematic, uniform approach has created a generation of players who are not rough enough around the edges, and lack the right mentality at decisive moments. 
It is a criticism which Horst Hrubesch, who managed the U21s until last year, has levelled at the side England will play on Tuesday.
'This team is good enough to become Under 21 European Champions,' he told Kicker. 'But they must prove it. Players like Dahoud and Meyer need to take responsibility, because at the moment we have too few real characters.' 
Nonetheless, it is a luxury problem in a team packed with talent. The fact remains that, if England can beat Germany on Tuesday, it is as sure a sign as any that the FA are on the right track with St. George's Park and the cultivation of their own young talent.
The latest products Germany's youth conveyor belt is constantly producing new talents, and several have made the jump from obscurity to stardom in the last couple of years. 
Julian Weigl was signed for Borussia Dortmund two seasons ago, and immediately matured into the side's key midfield director. 
Though his gangly frame and baby face betray his youth at just 21, Weigl plays with an astonishing maturity and intelligence. Only injury has kept him out of the squads for the Confederations Cup and U21 European Championships. 
Joshua Kimmich made a similar jump under Pep Guardiola at Bayern Munich. Another Stuttgart product, Kimmich has developed into an extremely useful all-rounder, and is pipped to fill the boots of Philipp Lahm, who retired at the end of last season. 
Fellow former Stuttgarter Timo Werner, meanwhile, has exploded at Leipzig this season. 
His 21 goals since moving to Leipzig last summer have earned him a place in Germany's Confederations Cup squad. 
Despite their youth, these players already have a new generation breathing down their necks, many of whom will face England on Tuesday night.
