Here is what i know.
Well dynamo moscow,go to the site of Fedcom,and who will see that this Fedorychev has a lot of money,Dynamo spend 55 millions of euros in new players,all from the portuguese league.Also fedcom is the sponsor of monaco.Fedorychev also wants want to build a new stadium.
I think overall dynamo moscow is the team with more money in eastern europe along with shakhtar donetsk(ukraine).
Cska moscow, sponsored by the fifth bigger oil russian company(sibneft),Abramovich is the major share holder of this company.
Spartak moscow,well just sponsored by the biggest private oil company in russia lukoil(since the end of Yukos or whatever you want to call it).If they wanted they could put Spartak european champion.
Lokomotiv moscow,sponsored by railways of Russia,not so much money like the others tree, but a well organised club.
Zenit st.petersburg,sponsor only by the biggest gaz company in the world(Gazprom),I think in some years time they will be so rich as the tree big.
Fk moskva,also a lot of money coming,they want to be russian champions in 2007,sponsored by Nickel Norilsk.
Saturn ramensoye,the have a sponsor(nafta moskva) that gave them 60 millions of dollars in ten years.These company wants to buy As Rome for 450 miliion of euros
Also we have Krylya Samara,but they are with some money problems in this moment.
Also we should not forget Torpedo because Alioshine will not live forever,so maybe a russian oil or gaz company will sponsored them.
Rubin Kazan also have some money.
Final note,Russia is the second country in terms of production of oil,and first in gaz production in the world.
The big problem for the russian football is the political situation in that region
