The France international is continually being linked with a move to a bigger club and has now caught the attention of the Catalans, who are on the look-out for young stars
The Blaugrana are keeping tabs on a number of young players with an eye on the future, and it is believed that the 21-year-old M'Vila is one of the top names on their wishlist.
M'Vila is a product of the Rennes youth academy and has made over 100 official appearances since making his first-team debut in 2009-10.
The holding midfielder, who has already been capped for France at senior level, has previously been linked with clubs such as Arsenal, Inter and Real Madrid.
His current contract with Rennes runs until the summer of 2015, and an offer in the region of €20 million could be needed to lure him away from his current club.
Starting last month and continuing every Friday through to January, Goal.com will publish extracts from Graham Hunter's highly-anticipated book, Barca: The Making of the Greatest Team in the World. The most recent extract detailed how Jose Mourinho's Real Madrid have closed the gap on Barca following a period of Catalan dominance.
