At the begining of the match, they put the starting lineups on the TV graphics. There was a definite dearth of vowels in both the Polish and Russian names. Turned out to be a pretty good game. Looked like there was going to a bloodbath outside the stadium before the kickoff, between the fans.
"Błaszczykowski" sounds just like it's spelled.
It's the effects of the cold climate, Emanuel. To say a vowel you must open your mouth wide and subsequently release some precious body heat.
