Season in bold means the team is champion that year, number of goals underlined means the player has been the best scorer of the championship this season
I am looking at transfermarkt.com. According to their stats he has scored 12 goals that season. I guess maybe one of these goals is classed as an own goal by other sources?
Ok, I will take a look again when I will update this quiz. But yes I've already sen this kind of difference because of own goals like you said. I well see. In any case, thank you for you feedback
