his first name is pronounced has Tom-ash
his surname pronounced Koo-shack 
yeah first name is pronounced like you wrote, but with the surname is a bit different. it's should be sth like: Kooshtsack. (you missed sound of "CZ" but it's duficult to write you'll have to hear it). Well, Polish has quite bad pronounciation for foreigners

Maybe he'll play next NT game, 'cos Artur left the team after Saturaday's game.
