Goalkeeper Lennart Moser has left 1. FC Union Berlin to join Belgium top-tier side KAS Eupen.

The 22-year-old hails from Berlin and has been part of the Union system for the best part of a decade. He played 46 competitive matches for the youths before coming into the professional squad to develop. He has enjoyed loan spells at Energie Cottbus, Cercle Brugge and Austria Klagenfurt over the last two-and-a-bit seasons.

"Leaving Union is very difficult for me. I found my footballing home here at the age of eleven and was part of this club for seven years. I am grateful to those responsible for the trust they have placed in me and wish 1. FC Union Berlin all the best for the coming season. At KAS Eupen, I now have the opportunity to further show myself with regular playing time," added Moser.

"We thank Lennart for his time at 1. FC Union Berlin. He was developed here and showed that he has the potential to become a regular goalkeeper. At KAS Eupen he now has the opportunity to prove this and gain match practice again," said Oliver Ruhnert, 1. FC Union Berlin's Managing Director for Professional Football.
