The Rockets booked their spot in the last 16 of the tournament thanks to a second-half strike by Chidi Kwem.
Ramovic praised the side for getting the win on the night and adds they still need to improve.
"It was a tough time, a tough pre-season for the guys, we worked a lot, of course we still have to improve but I have to give my team a huge compliment," Ramovic told SuperSport TV.
"They played well, they wanted to create chances. I think we also started well but it's a game now we can be happy but tomorrow we have to start again because we have 13 other games in the league. We have to improve, we have to get the points, I hope everything will be fine.
"We worked a lot to press, I was happy about it. But I also have to congratulate Chiefs, they played well, they are a tough team, they have an outstanding coach, I'm just happy to win. I hope to get only one percent of the success Baxter have and I will also be happy as a coach.
"It was the right step in the right direction, we still have to improve to the point of how I want us to play, we just have to keep the ball more, play the ball with more braveness, not just hit the ball long but it's a good start," he added.
