Speaking to Werder Bremen club media, Hein said: "The decision to move to Werder was very easy for me. It being such a big club with fantastic fans and a great stadium, I didn’t have to think twice. I’m really looking forward to getting started in Bremen."
THE BIGGER PICTURE
Hein’s move comes amid uncertainty in Bremen’s goalkeeping ranks, with young starter Mio Backhaus yet to make a Bundesliga appearance. The 23-year-old could step in if Backhaus struggles to adapt, having already racked up 32 La Liga appearances last season with Real Valladolid. For Arsenal, the loan offers valuable development for Hein while maintaining depth in the position for the future.

Bremen’s goalkeeping coach has hinted that competition will remain open, giving Hein a potential pathway to regular minutes. Arsenal will closely monitor his progress as they weigh long-term options between the sticks.
