The France Under-21 player found first-team chances hard to come by last term in Ligue 1 under former United defender Laurent Blanc so he spent the second half of last season on loan at Lorient, where he featured 15 times scoring just the one goal. Several other big guns across Europe have been tracking the player who can play in midfield or as a second striker.
"There is a very strong likelihood that the deal will go ahead," said Triaud to L'Equipe.
"Manchester United want to sign him and, for our part, we would be delighted to see Gabriel playing for such a prestigious club.
"We will make the official announcement when the time is right."
Obertan, who made his professional debut for Bordeaux when he was just 17, is seen as one for the future by Ferguson and a player with the potential to develop quickly at Carrington.
