The German stopper has been a Blues player since the summer of 2018 after leaving Borussia Dortmund where he had been a regular for their Under-19s side.
After making 12 appearances for Blues Under-23s during the first half of the 2018/19 campaign, the Neumunster-born keeper signed on loan for Hungerford Town in the National League South, the sixth tier of English football.
He earned some rave reviews during his 20 outings for the Crusaders, helping the Berkshire club complete what had seemed an unlikely escape from relegation when he’d initially joined them at the turn of the year.
