Former chelsea player ivanovic drops and breaks russian cup during celebration

I think you may be mistaken. Branislav Ivanović is a former Chelsea player, but I couldn't find any information about him dropping and breaking the Russian Cup during a celebration.

Ivanović is a Serbian professional footballer who played for Chelsea from 2006 to 2017 and was a key player for the team, winning several titles including the Champions League, Europa League, and Premier League. He has also played for Zenit Saint Petersburg in Russia, but I couldn't find any reports of him breaking the Russian Cup during a celebration.

It's possible that you may be thinking of a different player or incident. If you could provide more context or clarify what you're referring to, I'd be happy to try and help you further.
