Barcelona forward Neymar will stay at the club for "the rest of his life" according to director of football Roberto Fernandez, as Manchester United's interest looks set to relent. The Brazil international looks set to agree a deal until 2022 worth £150m a year.

The 23-year-old confirmed during the summer that he was approached by Louis van Gaal's side. The former Santos youngster's current deal expires in 2018 and with rival clubs circling, the Nou Camp side are looking to cement the future of their star asset.

United made an audacious bid for Neymar as they chased a striker during the off-season. Though that pursuit ended with the signing of Anthony Martial, any hopes of reigniting their interest in Neymar has seemingly been stifled by Barca's intention to nail the player down to a new deal.

"We are currently working on Neymar's contract extension and I don't think there will be any type of problem," Fernandez told Marca. "I have no doubt in my mind that Neymar will spend the rest of his life at Barcelona.

"Contract talks haven't broken down," he added. "We'll reach an agreement with him sooner or later, this season if possible. He has what it takes to win the Ballon d'Or. He's the second best player in the world after Messi."

According to The Sun, United made a £165m offer for Neymar during the summer transfer window, only to see their interest rebuffed by the Catalan giants. Neymar played a central role in Barcelona winning the treble last season, scoring in the Copa del Rey and Champions League finals against Athletic Bilbao and Juventus.

Van Gaal was forced to resort to signing Martial on the final day of trading in the transfer window, however the France international has been a revelation this term. Martial has already scored four times for United, including on his debut against Liverpool to propel the club into title contention.
