With an average age of just 24 years, four months, and a combined total of 179 international appearances, Germany have the most youthful squad of the eight Confed Cup teams.

On the back of his breakthrough season with RB Leipzig, striker Timo Werner, 21, expects a fiery start in Sochi for the untested, green Germans.
"We don't all know how fit we are after a long and hard season," admitted Werner.
