Category/Post Templates

First of all thanks for taking the time reading this and maybe helping me out.

I’m currently working on a sports news site. Currently for each country I have a different category template. Say you click on a news from England national football team (soccer) at the of the page it includes a graphic with the english flag.

What I want to do now, is to be able to do the same thing but with posts. I want to divide each country by leagues and by teams. When you click on a news link from Manchester United the post should have a graphic from the team at the top.

Here is where my problems begin. When I have the same post on a different category, the page repeats the same news page below it.

Here is a link where you can see what I mean: https://www.mym2webdesign.com/futbolalrojovivo/argentina/milito-me-termino-dando-la-razon-al-convocarlo/

Thanks in advance. Hope somebody can help me out.
