The opening stages of the match were certainly not for the purists; both sides could barely string more than a few passes together and instead exchanged petty fouls and misplaced passes.
It was starting to look like an extremely uneventful first half would end goalless, but Ismail Jakobs tore up that script when he side-footed home a few minutes before half-time.
If Balogun played a minor role in the opening goal - his presence in the middle of the penalty area forced the Reims defenders to leave Jakobs unmarked at the back post - he was the protagonist of the second.
Play had barely restarted when the 22-year-old found himself with grass to run into on the right of the box. Youssouf Fofana slipped Balogun in on goal and he kept his cool to rifle into the roof of the net, albeit via a slight deflection.
The youngster held his hands up in apology to his former fans, but moments later he was celebrating another goal. This time strike partner Wissam Ben Yedder applied the finishing touch, heading home Jakob's dangerous cross across goal.
Reims pulled one back from the penalty spot through Teddy Teuma, but it was Balogun and Monaco who emerged victorious in northeast France.
