Barcelona president Josep Maria Bartomeu is confident Manchester United target Dani Alves will make a U-turn on his decision to leave the Nou Camp after confirming the Spaniards have made him "a respectful contract offer" to commit his long-term future to the club.

The Brazil international's future at the Catalan giants has been under increasing scrutiny in recent months. His contract expires on 30 June.

Barcelona were reportedly ready to let him go at the end of the current season after the 32 year old experienced a dramatic drop in form over recent seasons.

But after Alves returned to his best under new manager Luis Enrique this year, the club have been trying to convince him to stay.

Alves, however, believes he has been treated disrespectfully by his club during past season and, after rejecting all the approaches to extend his contract, recently suggested he will leave the Champions League finalists once his contract expires on 30 June.

"There has been a lot of rubbish written, which I have been forced to put up with, and when push comes to shove, I have to come out and defend myself, and say what I have to say. I am with the team 200% but with the board about 10%. As it is, I have one foot, half a body and almost my head out of the club," Alves revealed.

Manchester United, Liverpool and Paris Saint-Germain have been reportedly monitoring the situation.

But after Alves himself ruled out a move to the Ligue 1 side and with the Merseysiders out of the next Champions League, several reports have claimed Louis van Gaal's side are in pole position to secure his services.

However, Bartomeu is still confident Alves will rethink his plans after saying Barcelona have made a "respectful offer" to keep him at the Camp Nou next season.

"We have made Dani Alves a really respectful offer," Bartomeu said, as quoted by Sport.

"He knows that, but the decision is his. If you ask me, I would say to sign it, because it is a good contract with Barcelona, who are considered the best club [in the world]."

Earlier this week Lionel Messi and Neymar urged the club to make an effort to commit the long-term future of the full-back.
