St Etienne are currently on an eight-game unbeaten streak in the league and have a Coupe de la Ligue final as well as a Coupe de France quarter-final in the coming weeks.
Hamouma said that the confidence in the team at the moment will be more important than any tiredness that might start to set in.
"I feel good and I'm playing without apprehension," Ligue1.com quotes Hamouma as saying. "The squad is full of confidence and putting together very good results.
"We've got common objectives and as long as we stay humble we are capable of achieving beautiful things. We've got a strong squad that's full of quality.
"We prefer playing in all three competitions than just coming in to train. The Rennes match is just one of 38 league games and we're not thinking about the Coupe de la Ligue final just yet."
Hamouma has four goals in 21 league games this season.
