The 22-year-old is coming off the back of an impressive season at club level which saw him collect a Premier League and Carabao Cup double.
He will, however, play no part for his country in Russia this summer after being cut from Joachim Low’s 27-man preliminary party.
With that selection narrowed down to 23 ahead of the defence of their global crown, Germany have opted to favour the likes of Julian Draxler and Sebastian Rudy.
Arsenal playmaker Mesut Ozil was among those to receive good news, though, while Chelsea defender Antonio Rudiger will be another Premier League performer within the ranks.
Bayern Munich goalkeeper Manuel Neuer gets the nod despite his recent injury struggles, while Borussia Dortmund forward Marco Reus will get the chance to put his previous fitness issues behind him – with the 29-year-old having missed out on the successful World Cup campaign in 2014.
