The Czech football federation claims Josef Bican scored 821 official goals and not 759, meaning Juventus forward Cristiano Ronaldo has not broken his record.
The Portuguese superstar scored his 760th career goal in the 2-0 win over Napoli in the Supercoppa Italiana on Wednesday.
Opta has registered 759 goals for Bican and Ronaldo thus broke his all-time goalscoring record for club and country.
But the Czech football federation published a statement with an updated number and claims Ronaldo must score 62 more goals to overcome their hero.
