It's an interesting question. There are some exceptions for lawful processing under GDPR[1]:
> Processing shall be lawful only if and to the extent that at least one of the following applies:
> processing is necessary for the performance of a contract to which the data subject is party or in order to take steps at the request of the data subject prior to entering into a contract;
> processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller;
So in this case, it's probably the case that any athlete will have to sign a contract saying they are OK sharing their stats publicly in order to play. If an athlete sued Eredivisie to try to be forgotten from the league tables, how would that case be decided?
It's also worth noting that in the original "right to be forgotten" case that Google lost, the original newspaper articles reporting the criminal cases were not required to be expunged, so there is still a "public interest" defense for keeping information about people in public. It's certainly unclear exactly where the boundary is on that though.
I wonder also if there is an argument that a professional player's stats are not Personal Data; those stats are a record of events that occurred in public, while engaging in a performance. IANAL so interested in opinions of more knowledgable folks on this one.
