Barcelona president Josep Bartomeu insists Lionel Messi will be offered a new contract to keep him with the Catalan giants.

The Argentinian superstar has been linked with a move away from the Nou Camp after an injury-hit campaign has seen Messi fail to reach the heights of previous seasons.

However, Bartomeu believes criticism of the 26-year-old has been harsh, and the Blaugrana will do everything in their power to ensure he remains at the club.

"Messi is under contact until 2018," Bartomeu told TV3.

"But we want to improve it to adapt to football's current situation.

"I think people are being unfair on Leo Messi. He has led us to so many wins in recent years.

"He has led the team and done so very well and we have no doubt that he will continue to lead the club into the future.
