He began his football career in Istanbul soon after his family moved to Taksim, Istanbul in 1937. He joined Galatasaray when he was 16 years old in 1947. Rober said "After I played for different amateur teams in Istanbul, I was wanted by Pera (Beyoğlu) and Taksim football clubs. I did not wanted to play for any of them. Because, at the time, only ethnic minorities used to play for these two teams. As I am a none-Muslim, I was advised to play for one of these two teams. I refused this as I felt that I am a Turkish. Therefore, I decided to play for Galatasaray. I wanted to prove that as a Turkish citizen, I am not different. I proudly proved this by playing Galatasaray and National team.
