National soccer player Kai Havertz missed a win on his debut for Arsenal.
In the 1-1 (1-0) test match at second division club 1. FC Nürnberg, the 24-year-old came on at half-time on Thursday, but remained quite pale.
Havertz recently switched from Chelsea to city rivals for around 75 million euros.
Bukayo Saka (7th) gave the favorites an early lead, Kanji Okunuki (62nd) equalized in the second round.
In the Premier League, Arsenal and Havertz start against Nottingham Forest on August 12.
