Re: FIFA 13 and Ultimate Team Discussion
Don't know how this would happen without you doing this...
Editing the National teams, and replacing Drogba with someone else so that he's no longer in the Ivory Coast squad and ends up in the Free Agents section. Then you go to Club Transfers and transfer him to CSKA Moscow. That'd be the only way he'd show up there.
Think you're thinking of Doumbia.
I just checked this and he's there for a lot of people. In a career mode they probably put him as a free agent and the first team who buy him are CSKA all the time. You can check this in "buy players" in a career mode, do the search for all the players with the highest rating from 94(Messi), Drogba is 85.
