A goalkeeper who frequently represents Estonia at senior level, Hein gained experience of first-team football at club level last season.

Hein has been named on the bench for the Arsenal first-team on numerous occasions, including against Brentford in the Premier League last season. He also featured for the Gunners in pre-season in 2021.

A fine shot-stopper, he caught the eye during a loan spell at Reading in the second half of the campaign before injury stopped him in his tracks.

Signed from Nomme United in 2018, Hein has progressed well during his time at Arsenal.
