Nasko's last period as a Levski football player ended with the remarkable 12 goals in 10 games. Although for half a season, Sirakov turned out to play a key role in the jubilee, 20th championship title of the "blues", after scoring the unforgettable four goals in the historic 7:1 over CSKA and a hat trick in the 6:1 over Botev (Plovdiv). To this day, fans are still wondering what would have happened if their favorite player had stayed at the Gerena stadium in the spring season as well?
