The former Paris St Germain ace has been linked with the cream of top European clubs with price tags ranging from £20 million to almost double that.
Dembele, who is currently sidelined with a hamstring injury, enjoyed a sensational opening season with the Champions after netting 32 goals in all seasons.
Moneybags Marseille are desperate to challenge PSG in Ligue 1 this season and have long been linked with Dembele.
And the French giants’ president Jacques-Henri Eyraud finally confirmed the 21-year-old is on their list.
He said: “Moussa Dembele is a young player with power and speed and he is interesting.
“It’s no secret that we are actively looking for a striker. It’s a difficult area to get players.
“I try to avoid talking for the manager or the Sporting Director when it comes to players, but I have obviously have my own ideas.
“All I can say is that he is an interesting name.”
