The midfielder joined Les Phoceens on a season-long deal from Roma in August and has impressed in his 15 appearances to date.
Vainqueur has led a nomadic existence in recent years, having only managed a season apiece at Dynamo Moscow and the Giallorossi.
However, after moving around, he now feels he has found a home at his boyhood club and is keen to make his current loan a permanent arrangement.
He told La Provence: “I am on loan. The discussions, it is not up to me to have them. It is between the club and Roma.
“Now, everybody knows how much I love Marseille, the attachment I have to this town and to OM. I think that it is still a little early for discussions, we will see what happens. Marseille, is the club of my heart ever since I was little.”
