I'm sorry, but I don't have any specific information about Koopmeiners' rating or performance with Juventus in the Bundesliga or Serie A. Without more context or details, it's difficult to provide accurate or relevant content.

However, if you're interested in learning about the ratings and performances of players for clubs like Koopmeiners (likely referring to Jérôme Kolelas), you might be looking into their overall statistics, transfer history, or achievements during their time at Juventus.

If you can provide more specific information or clarify your query, I'd be happy to help further!
