BranislavIvanovic followed in the footsteps of his father by becoming a professional footballer in Serbia. He started his career at FK Srem before joining OFK Beograd in December 2003.
OFK Beograd was in the Serbian top flight by the time BranislavIvanovic joined them and he was a part of the team that punched above their weight for several seasons. Ivanovic and OFK Beograd performed beyond expectations and they even reached the last four of the 2004 UEFA Intertoto Cup against all odds. They were not one of the teams expected to make the final stages of the competition.
