Eryol 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 want to play for any of them. Because, at the time, only ethnic minorities used to play for these two teams. As I am a non-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 for Galatasaray and the national team."
