Valbuena has been one of the stand-out players at the World Cup so far and is currently preparing with the France national side ahead of their quarter-final tie with Germany.
The report states that Marseille are willing to listen to offers for the 5"1 winger with a bid of around £8m seemingly enough to enter talks with the player.
Sunderland are yet to splash any cash so far this summer, but have recruited no less than four players on free-transfers.
There is certainly money to be spent at the Stadium of Light, and Gus Poyet will be keen on bringing in some real quality ahead of the upcoming campaign.
Valbuena has spent eight years of his career at Marseille making over 200 appearances and scoring 25 goals for the French giants.
He was part of the team that won the French league in 2009-10 and has won the country's domestic cup three times.
If reports are to be believed then incoming manager Marcelo Biesla clearly considers the midfielder to be surplus to requirements at Marseille.
At the age of 29 Valbuena is running out of time to ply his trade anywhere else but France, and could be open to offers from abroad.
Unfortunatley for Sunderland whilst there's no doubt that Poyet would jump at the chance to take the the midfielder, it's extremely unlikely that a player of Valbuena's quality visions his future on Wearside.
After such an impressive showing in Brazil, it's more probable that the Frenchman will make a move to one of Europe's more elite clubs.
