The strike was Ronaldo’s 760th for club and country, with Bican said to be one back on that mark. Pele is placed third on the list with 757 goals to his name, fellow Brazilian Romario in fourth with 743 and Barcelona icon Lionel Messi completes the top five with 719.
The Czechs however are taking issue with claims that one of their own has been usurped.
For them, Bican – who shone for Rapid Vienna and Slavia Prague between 1931 and 1955 – remains out on his own.
They have his tally sitting well above the mark Ronaldo has just passed, with a further 62 efforts being added to his haul.
