Lepaul, 25, has 14 Ligue 1 goals, placing him third behind Mason Greenwood (15) and Joaquín Panichelli (16). With seven games left, he is determined to finish as the league's top scorer.
The Rennes forward said the prize would be "magnificent" and that scoring in Ligue 1 is hard. He is focused on his personal objectives rather than a national call‑up, while Rennes sit seventh and chase European qualification.
