Josep Maria Bartomeu, vice-president of Barcelona, says Lionel Messi is not interested in money as the club prepare to enter into contract negotiations with the Argentine superstar.

Messi's current deal at the Nou Camp run until the summer of 2016, but the Catalan giants are keen to improve the 25-year-old's deal during the current campaign.

The Barcelona forward is somewhat surprisingly only the ninth highest earner in world football in terms of salary, according to Marca, and reports climb he will ascend the rankings with improved terms.

Bartomeu, though, has stressed that Messi is not driven by money, but the project that is in place at Barca while retaining the ambition to achieve further success with the club he joined as a 13-year-old.

"Messi was born here as a professional. He grew up with the project, he believes in the project and he's the leader of the project. Money comes later. He wouldn't be so happy at any other club," Bartomeu told La Graderia.

"The Barca dressing-room is really close-knit. The players get on very well and there's a good relationship with the fans in the stands. The people are continuing to enjoy things and the titles will come."

Messi has already scored ten goals for Barcelona in all competitions this season, while his six strikes in La Liga have helped Blaugrana move eight points ahead of Real Madrid after only five games.
