Dan Kolov who was undefeated in all of his over 1500 official matches is the greatest wrestler of all time. His nicknames are „King Kong“, „The King of Wrestling“, „Bulgarian Lion“, „Balkanian Lion“, „The Steel Hands“. People call him „One true giant, in strength and spirit". Throughout his whole career he is asked many times to change his citizenship to American. He refuses it with the words: „Dan Kolov is Bulgarian“. Dan Kolov remains proud Bulgarian until his death and is famous for his words: „I feel strong, because I am Bulgarian“. For him his motherland is the most holy and sacred thing. Also, he is famous with another memorable saying, upon his return to Bulgaria, he was asked if he wants someone to take him home by carriage, to which he replied: „I left home walking, I will go home walking!“. In the last year of his life, already very ill, the Balkan lion confronts much younger champion Al Pereira and even then remained a man of honor - was able to beat him.. He is buried, with a specific request, facing the 'Balkan'- "Balkan against Balkan", as „Balkan“ in Bulgarian means „mountain“ - „Mountain against Mountain“.
