2017 UEFA European Under-21 Championship - Squad Analysis
TSZ has looked at all UEFA European Under-21 Championship squads to analyse the domestic contributions of each nation's players during the 2017/18 season.
* = The Swedish domestic league is played through the summer months, so numbers are affected by this fact.
First, we look at the number of domestic appearances amongst each nation:

- Germany, who have set the standard for developing young talent in the last decade, top this particular chart.
Notable Players
Tammy Abraham (England - 41 appearances)
John David Swift (England - 39 appearances)
William Hughes (England - 39 appearances)
Inaki Williams (Spain - 38 appearances)
Mikel Oyarzabal (Spain - 38 appearances)
Luca Garritano (Italy - 38 appearances)
Alessio Cragno (Italy - 38 appearances)
Gianluigi Donnarumma (Italy - 38 appearances)
If we drill this data down into on-field minutes, this is how the chart is affected.

- The German squad still leads the way in this respect. Denmark have jumped into second here, whilst England remain in the middle ground.
Notable Players
Tammy Abraham (England - 3425 minutes)
Alessio Cragno (Italy - 3420 minutes)
Gianluigi Donnarumma (3420 minutes)
Now we look at the number of domestic goals scored by players in each squad:

- Young Danish strikers have propelled their country into first place in this chart, whilst England fare better here and sit in second place. Germany are surpassed by a number of nations in terms of goals scored, perhaps due to the fact that their under-21 domestic appearances are more evenly spread around different positions.
Notable Players
Urros Durdevic (Serbia - 24 goals)
Marcus Højriis Ingvartsen (Denmark - 23 goals)
Tammy Abraham (England - 23 goals)
Tomas Chory (Czech Rep - 16 goals).
