Players from different country - any problems?

Hello,
Here is my question. I have many players from different countries. Usually only 4-5 are from same country (Poland) while playing a match and rest for example Brazil, Argentina etc. And my question is that there are any problems with communication between players? Better have more from one country (same language) to have better communication? Or this isnt any problem and doesnt matter?

I really don't think the game is that advanced that it takes languages into account.
I have players of various different nationalities and there never seems to be a problem.

agreed...

its not something ive ever noticed either...they're all the same irrespective of country imo...

Ok, thx for fast answer:)
