The winger could be on the move ahead of the 2020/21 campaign and has attracted interest from Carlo Ancelotti’s Everton.
Bouanga, who scored ten goals in 26 Ligue 1 appearances for Saint-Etienne this season, is also on the shopping list of Spanish side Real Betis.
Rennes though are hoping to keep the 25-year-old in France and the club’s new sporting director Florian Maurice has confirmed their interest.
Asked about the winger at a press conference, Maurice replied: “Denis Bouanga is one of the players identified in specific positions.”
Rennes finished a lofty third in Ligue 1 this season and a move to the club would hand Bouanga an opportunity to play in the Champions League.
Bouanga is not expected to be a cheap option for Rennes though, with Saint-Etienne having already indicated they are looking for €15m to let him leave.
Les Verts splashed out €4.5m to sign Bouanga from Nimes just last summer.
