According to reports in Germany, Bremen are ready to activate the purchase option in Hein's loan deal with Arsenal. The move is expected to cost around three million euros.
The 24-year-old Estonia international only made two appearances during the campaign, but his performances convinced the club that he is ready for a bigger role next season.
Bremen now see Hein as their future first-choice goalkeeper, and that decision appears set to open the door for Mio Backhaus to leave the club this summer.
Backhaus enjoyed a strong season and has attracted interest from several teams across Europe. Reports in Germany suggest Bremen could demand around 15 million euros for the 22-year-old goalkeeper.
The club's plan would represent a major change in goal ahead of the new campaign, with Hein expected to take over as Bremen's number one if the transfer is completed in the coming weeks.
