Goals from Justin Shonga and Thembinkosi Lorch helped the Soweto giants secure a 2-0 victory over struggling Dikwena, who remained 16th on the PSL standings.
The victory took Pirates to second spot on the table as they extended their unbeaten run to four matches in the league.
"I believe we controlled the match from start to finish. This is a special day for us at Orlando Pirates - in the 27th minute, 27th of January Justin Shonga scored the goal [Shonga wears jersey number 27]," Sredojevic told the media after the game.
"Today is the 70th birthday of our chairman [Irvin Khoza] on behalf of the technical team and my players we wanted to wish him happy birthday and there's no better way than winning today's game," he continued.
Shonga opened the scoring in the first-half with a decent header and Lorch sealed the Buccaneers' win with a great finish.
"We were playing as per the instructions. We opened the game at the right time. The second goal practically killed off the game. I'm very happy we got the three points. The players worked really hard during the week. We deserved this today fully," he continued.
Sredojevic explained the celebration he made with Riyaad Norodien in the second half as his Soweto giants kept their hopes of challenging for this season's PSL title alive.
"We are having good spirit. We love each other we love the jersey. We want to do anything for this team. The first platform is to have good spirit. The celebration was like in basketball where we were beating each other with the chest. So it's our way of celebrating and showing that we are in good track," the Serbian added.
"Happy birthday to the chairman and this win is for the supporters, for us we have already forgotten and we are focusing on our next game on Wednesday against Ajax Cape Town in Cape Town," he concluded.
