During his managerial career, he was nicknamed The Saviour for his profound record of saving club from sticky situations.

[1] He first appeared on Kantrida, his future club's ground, in 1954 at Kvarnerska Rivijera, where Red Star beat Rijeka 3:1 in the final of the tournament.

He finished his career playing for the low-tier Belgian clubs Racing Jet and Tilleur.

[4] Naumović made his debut for Yugoslavia in an October 1963 friendly match away against Romania, coming on as a 68th-minute substitute for Slaven Zambata, and earned a total of 3 caps (no goals).

His final international again was a friendly against Romania but since the Romanians played with their Olympic squad both games are unofficial.
