The day of the Northern Ireland match is the anniversary of the debut appearance in the Germany senior team for Kai Havertz (three caps). A year ago, on 9 September 2018, the then 19-year-old was brought on in the 2-1 win against Peru by Germany coach Joachim Löw with two minutes to play. U21 European Championships runner-up Jonathan Tah (six caps) was in the squad then but did not play.
In addition to the Germany duo, 12 other Werkself players are on international duty in the coming week: Julian Baumgartlinger (68 caps) and Aleksandar Dragovic (74 caps) have been selected by Austria head coach and former Bayer 04 player Franco Foda for the two Euro qualifiers against Latvia (6 September) and Poland (9 September). Lukas Hradecky (53 caps) also faces two Euro qualifiers with Finland – the 'Eagle owls' play Greece (5 September) and Italy (8 September).
Lucas Alario (three caps) has been called up by Argentina for the first time in two years. And that is for the two friendlies against Chile (6 September) and Mexico (11 September). That could mean the Werkself number 13 coming up against team-mate Charles Aránguiz (74 caps) who is expected to be in the Chile line-up. In addition to the game against Alario's Argentina (6 September), Chile also play Honduras (11 September).
For Leon Bailey (four caps) and Jamaica there are two matches in the CONCACAF Nations League: The 'Reggae Boyz' play Antigua & Barbuda on 7 September and Guyana on 10 September.
Paulinho (Brazil U23), Moussa Diaby (France U21), Panagiotis Retsos (Greece U21), Adrian Stanilewicz (Poland U20) and the two U19 players Mark Lamti (Tunisia U23) and Marcel Lotka (Poland U19) are on the road with their junior national sides next week.

Bayer 04 Leverkusen have extended the contract with U19 goalkeeper Simeon Rapsch. The Germany youth international goalkeeper has signed a long-term contract with the Werkself running to 30 June 2029. The 18-year-old joined Leverkusen from FC Viktoria Köln in the summer of 2024.
