Germany coach Stefan Kuntz selected Wirtz for the Germany U21 squad for the first time for the Euro qualifiers against Moldova on 3 September and Belgium on 8 September. In agreement with Bayer 04 head coach Peter Bosz, Kuntz will now manage without the 17-year-old.
"Of course, we have important games in September. Nevertheless, we look at each individual player to decide what's best for his current situation and further development. We would have been very happy to have Florian Wirtz with us. But that doesn't make sense at the moment with the break after the Europa League tournament. He first needs to have a decent pre-season before his first U21 internationals," explained the Germany coach.
In the case of Panos Retsos, who should be joining the Greece U21 squad for the two Euro qualifiers against the Czech Republic and San Marino, Bayer 04 and the Greek FA have both agreed that Retsos should complete the pre-season ahead of the 2020/21 campaign with the Werkself and miss out on the internationals.
