Anova application question

Hello, I have a question regarding the application of Anova in the following paper:
It examines the relationship of the ownership status of football clubs with the performance in various financial indicators. The sample is from the premier league over 10 seasons. The way I understand it, the author creates cases for each club and its ownership status in a particular season, and then applies the anova analysis. But since this is based on panel data, therefore the observations are not independent, which is a requirement for anova. Why can this be applied here? Wouldn`t you need to apply anova with repeated measurements?
I am not not an expert so any help would be appreciated.
