Kai Havertz is heading back to Arsenal for treatment after picking up an injury during Germany's 1-1 Nations League draw with the Netherlands on Thursday.
The forward went off in the first half, with the issue understood to be a suspected muscle strain, according to Sky Sports. He will now be assessed by Arsenal's medical staff rather than remaining with the national team.
The extent of the problem and how long Havertz might be sidelined has not yet been confirmed, but the early withdrawal from international duty will raise concerns at Arsenal ahead of their busy fixture schedule.
