Thank you very much for your reply.
I did study Russian at university for two years (94&95) but sadly, I have not had a great chance to use what I learnt back then, hence my understanding of the Russian language today is as feeble as the SSSR defence in that Belgium game. But perhaps reading any of Vartanian's publications could help me revive my skills? I will definitely look into what he has to offer and from what I understand through what you're saying, he has produced some quality material on various topics.
Another aspect I am fascinated about is how players from smaller Soviet republics, such as Georgia, Armenia and sometimes Lithuania were able to make an impact on the international scene, among playes from Russia, Ukraine and Belarus. Obviously, with Dinamo Tbilisi being so strong for a sustained period of time, and I guess the same can also be said about Ararat Jerevan and, perhaps to a lesser extent, also Zalgiris of Vilnius, footballers from these republics were given the opportunity to play with the ones from the bigger republics in the Soviet national team. All these points are fascinating aspects of the past.
Thank you again.
