The 26-year-old has expressed a desire to leave the French outfit and any dealings are set to progress this week, according to the club's manager Elie Baup
The French outfit's president, Vincent Labrune, told Canal+ on Sunday that the defender has played his last game for the club, adding that the English top-flight is his likely destination.
The club's manager has re-enforced those claims, stating that the player no longer wants to play for Les Phoceens, while also suggesting a move could be closer by the end of the week.
"Things could progress during the week for M'bia." The Marseille boss told RMC. "It's clear for me and for him: he's shown his desire to leave.
"He is still available all the same because he had a good game at Montpellier. As long as he's here, he needs to do his best.
"But we need to find the best solution for the club."
The Cameroon international has been linked with QPR this summer, with Mark Hughes already having brought in a number of new faces as he aims to turn the London club's fortunes around after they narrowly avoided relegation last term.
Speculation also remains over Rangers' midfielder Joey Barton's potential loan move to the Ligue 1 side, which may be part of any transfer.
If any deal was to be done, M'Bia would be the second high-profile defender to leave the club for the Premier League this summer, with Cesar Azpilicueta's move to Chelsea being officially confirmed on Friday.
