What happened to Russian EL teams is not going to happen again. That was atrocious. That was a disaster, which will probably never repeat. In the CL, CSKA Moskva reached quarterfinals, Rubin did rather well in a group, which contained Barcelona AND Inter. As for RPL, in general, the inflow of large amounts of money had made RPL one of the strongest leagues. I have a very respectable impression of RPL. So, do not count your chickens.
