ترجمه - انگلیسی-پرتغالی - In my country everyone knows about CSKA.

CSKA - central sport club of the army

"Conhecem o CSKA" actually means "know CSKA", literally, it would be "know about = sabem do", but it is not common to be said like that. This is the most common form.
"CSKA - Central Sport Club of the Army = Clube Desportivo Central do Exército"
