Mammadov was well known for scoring the winning goal for Dynamo to clinch the Soviet Top League title for the club in the 87th minute of their 1957 championship match against
Spartak Moscow; 50 years later, Mammadov's strike was commemorated when he was awarded the
Order of Alexander Nevsky (first degree) at Dynamo's
Petrovsky Park. In addition to the 45 goals he scored as a member of Dynamo in league play, Mammadov also scored 11 times in international club play, including equalizers against
A.C. Milan in front of 100,000 spectators at
San Siro in 1955 and against the Brazilian side
Vasco da Gama during their 1956 friendly in
Moscow in front of 90,000 fans. In 1992, Mammadov became the first head coach of the Azerbaijani national football team, compiling a 3–1 record as coach that includes the first ever national team victory, over
Georgia, on 25 May 1993. For his contributions to Azerbaijani football, a football tournament was established in 2008 in Mammadov's honor, which was played in
Baku. ==Honours==
