Traore left Chelsea over the summer for Lyon, slating his former club's treatment of their academy players.
Speaking to Onze Mundial, Traore was asked about the prospect.
"Manchester United? Why not? I will work hard and if opportunities open, why not?" he smiled.
Traore also said of his experience with Chelsea: "I fought, I reached the first team. But, in Chelsea, for a player from the training centre, it's almost impossible to impose yourself as a starter. And I wanted to be a starter ... I'm proud of what I did there before I left.
"Leaving the academy, joining the first team and scoring goals in the pros, it's not bad."
