Schade has scored three goals in five Premier League appearances this season and started both of Jurgen Klopp's opening two matches as Germany manager.

The attacker initially joined the Bees on loan from Freiburg before completing a permanent £22 million transfer in 2023, which was a club-record fee at the time.
