AustriaA nivel individual, fue el máximo goleador del VfB Stuttgart en la temporada 2020-21 de la 2. Bundesliga, contribuyendo al ascenso del club. No ha ganado títulos importantes a nivel de clubes ni ha sido internacional absoluto con Austria de forma destacada.
Sasa Kalajdzic es un delantero centro austriaco de origen serbio, conocido por su imponente altura y capacidad goleadora. Inició su carrera profesional en el Admira Wacker de Austria antes de destacar en el VfB Stuttgart de la Bundesliga alemana. En 2022, fichó por el Wolverhampton Wanderers de la Premier League inglesa, aunque una grave lesión de rodilla frenó su progresión.
Kalajdzic es un delantero centro clásico de gran envergadura (2 metros), que utiliza su altura para ser un referente en el juego aéreo y en el juego de espaldas. Su principal fortaleza es el remate de cabeza y su capacidad para aguantar balones largos, aunque su movilidad y velocidad son limitadas. Es un jugador ideal para equipos que buscan un '9' de área que finalice jugadas con centros laterales.
