Kanchelskis was ethnic Lithuanian, born to Ukraine, but picked Russian nationality after the collapse of the USSR.
I've never been convinced by Yarmolenko, but being made of glass kind of counts as flopping too
Well, if your argument is along the lines of "Ukrainian culture is too different from English culture, so people born and bred there won't succeed in England", then Kanchelskis is a good example of that not being true. There really haven't been too many Ukrainian players in the PL though. Zinchenko who's currently playing for Emirates Marketing Project looks like a proper player to me.
