Different widgets for different categories/sub categories

Hi

i have a question regarding my site https://www.the4thofficial.co.uk

i have an ePlayer that can provide different content for different teams/cup etc that i want to show on my site

is there a widget that can allow me to lace the eplayer on different sub-categories

for example if someone clicks on the Premier League>Arsenal option on the main navigation menu it will take them to all the articles in the Arsenal category but allow me to place the Arsenal ePlayer on the sidebar?

and in the same respect if someone clicks on the Premier League>Liverpool option on the main navigation menu it will take them to all the articles in the Liverpool category but allow me to place the Liverpool ePlayer on the sidebar?

i have seen Category widget but this only includes parent categories and not child categories?

does anyone know of a plugin out there that do the trick ??
