Players language!!

Was wondering in football manager does players language come into the game, like isit harder for them to interact with players on the pitch????

ive got a russian goal keeper called Edin Bower and he can not speak english yet, same as my new right back he does not speak english either.

my other 3 defenders are from england, so does this come into the game or not??? it would be good to know how it does aswell!

thanks.
