Aljoscha Kemlein: From bad luck with injuries to U-21 hope at Union!
The path of Aljoscha Kemlein, born on August 2, 2004, impressively shows how complex the career of a young professional footballer can be. The talented defensive player is currently playing for Union Berlin in the Bundesliga and has recently proven himself to be indispensable for the German U-21 national team. He has put in some notable performances in recent games, including an assist in the impressive 6-0 win against Malta and another in a 2-0 win against Georgia. The Daily Mirror reports that Kemlein has now been on the pitch as a regular player six times in a row.
But it wasn't always so smooth. Alyosha struggled with the after-effects of a foot injury for months. An operation in February threw him off track and paralyzed his playing time, so that he was only able to appear sporadically as a substitute until the end of October. He used this time to work on his fitness and face many challenges again. “I don't see myself at the same level as before the injury,” he said honestly to his coaches and fans, while remaining motivated to improve his threat in the attacking third. Wikipedia points out that Kemlein is regaining form after his injury, even though he has not scored any goals or direct assists for Union Berlin so far this season.
Recipe for success and return
Kemlein, who has been playing for Union since his D-youth days, underwent crucial development during his loan to FC St. Pauli in 2024. There he managed to establish himself in professional football, which was of great importance for his career. “I had a formative time at St. Pauli,” he estimates, adding that contact with his former club has decreased over time. The reason for this is the numerous changes within the team. Nevertheless, the contact with his childhood club and his connection to history do not go unnoticed.
His coach at Union, Steffen Baumgart, praised Kemlein for his tireless efforts and described him as one of the hardest-working players in the squad. A particular focus is on Kemlein's ability to act as a driving force for the team, especially in a style of play that is defined by hard work and defensive strength. His role will also be crucial when Union face St. Pauli on Sunday, a game that is high on Kemlein's priority list.
