Be swift and remove them. Putin is a sport fan (and a superior athlete from the hockey footage i've seen).
Let this mad man know that he does not have the support of the football world.
Putin couldn't care less about Spartak, Zenit is the football club that he cares about to any degree...though he isn't anywhere near as interested in Zenit as he is SKA because he's not a big football fan. So if the idea is to try & irritate him via sport, it's too late.
But this western focus on Putin badly misunderstands russia's internal dynamics. Putin isn't some mastermind who controls everything that happens in russia, he's a clever figurehead who the oligarchy & military elite can not agree on a replacement for because everyone has their own preferred candidate, nobody wants to let the other guy's pick get the job, and he's been a competent administrator to this point.
So focusing on Putin instead of the interests of the Oligarchy will never change the russian state's behavior. People just like the idea that if you could only take down Sauron the entire evil empire would disappear, but if you want to change the russian state's behavior then you need to focus on the interests of the oligarchy & military elite...with the former being more significant than the latter.
This war doesn't end by annoying one Russian, it ends when the oligarch's interests/plans in the black sea are secured against Erdogan's ambitions or the future of Nord Stream 2 is genuinely threatened...rather than simply being temporarily delayed.
If the Oligarchs become more worried about their plans for the Baltic than they stand to gain in the black sea, then they'll pull back, regardless of how much the military people want to re-establish the old buffer from NATO & shrink that european land-border that they have to defend.
