Lionel Messi is continuously being linked to a move out of FC Barcelona, but club president Josep Maria Bartomeu insisted that they are not planning to sell their superstar forward.

Messi, who is in contract with the club until after the 2018 season, has a €250 release clause in his deal with FC Barcelona, but several teams are reportedly willing to spend to acquire the Argentina international, including Manchester City and Paris Saint-Germain.

Earlier this month, FC Barcelona international sporting director Ariedo Braida admitted that they cannot rule out a deal that would send Messi to either Manchester City or PSG because both clubs have the money to make a serious run at Messi once he becomes available.

"I believe it's very difficult that Messi will leave Barca but at times in football strange things happen," Braida said earlier this month. "Now with these clubs that have so much money like City and PSG, certain amounts don't seem to have a value. In football things happen that appear impossible but I hope he will remain."

Reacting to the rumors about Messi, Bartomeu reiterated that they have no plans to part ways with the 27-year-old forward, who he thinks will spend the rest of his career at Camp Nou.

"Sell Messi? Impossible," Bartomeu said via Marca. "Anyone who says that is just trying to unsettle him. Leo grew up here, at Barcelona, and therefore he is going to retire here. I think that's what he wants too."

Talks about Messi's exit started when the club failed to express support to the four-time Ballon d'Or winner in his tax woes. Messi even admitted that his future at Camp Nou is uncertain because anything can still happen before his contract runs out in 2018.

Messi is also reportedly unhappy at Barca because of coach Luis Enrique. The two reportedly clashed in training in January, which intensified speculations about Messi's possible exit. Bartomeu admitted that Messi and Enrique had an argument earlier this year, but he thinks it is not a big deal because a player-coach discussion is a normal thing.

"They're just squabbles between coaches and players. It's normal," Bartomeu added. "It happens in any place of work. A good team progresses as the result of conflicts and finding solutions."
