Diawara, who was born in Conakry, has been in Italy since 2014 and has since secured an Italian citizenship starring with Bologna and Napoli in Serie A.
Since pledging his international allegiance in March this year, the player has yet to make his official debut, often pulling out of the squad through injury.
And claims were made that the defensive midfielder had a case of cold feet, with the Azzurri publically courting the 21-year-old's services.
But Diawara has quickly dismissed the claims in an interview with BBC Football.
"I have always dreamt of playing for Guinea because it is very important," he said. "I never said I would play for Italy."
He explained he was encouraged to accept the call-up after talking to Liverpool midfielder Naby Keita and the leadership of the Guinea Football Federation.
"I was not ready yet to come to the squad. The moment is here, now I am ready to play for my nation.
"I think Guinea can get to a high level because there are good players. I too will try to bring something and we will help each other."
