A product of the famous HNK Hajduk Split youth academy and one-time Croatian U16, U17 and U19 national team player, Goran began his senior career in 2004 on loan at HNK Trogir, then playing in the 1. Županijska liga Splitsko-dalmatinska. The club topped the table and moved to the 3. HNL – South and Goran played another season there. Dismissed from Hajduk as surplus, Goran played two more seasons in 3. HNL – South, first for NK Zagora Unešić and then NK Junak Sinj, where he was the star player in a season that resulted in their promotion to 2. HNL, catching the attention of some 1. HNL clubs.
He moved to HNK Šibenik, quickly becoming a first team player (50 first team caps in his first two seasons at the club).
In May 2010 he received his second call-up, for friendly matches against Austria, Wales, and Estonia, following the injury of Vedran Runje. Being the third choice, after Danijel Subašić and Stipe Pletikosa, he didn't get his cap that time.
With HNK Šibenik in financial difficulties, Blažević cancelled his contract with the club in December 2011. In January 2012, Blažević signed a four-year contract with Hajduk Split. As Hajduk's former first choice goalkeeper Subašić had just left the club for French Ligue 2 side AS Monaco, Blažević immediately was bestowed the first choice at the historic club.
In September 2013 Blažević passed successfully his medical and signed a 2-year contract with Bulgarian side Levski Sofia. He quickly became first choice at the expense of Plamen Iliev, but gradually lost his starting spot following the appointment of Antoni Zdravkov.
