Southampton defender Nathaniel Clyne is reportedly going to reject a new deal at the St Mary's in order to force a move to Manchester United.

The 23-year-old fullback, who moved from Crystal Palace to Southampton for an undisclosed transfer fee in the summer of 2012, has a year remaining on his current contract at the St Mary's.

Due to this reason, there has been a lot of speculation on the defender's future, with several clubs believed to be interested in his signature.

Southampton, who are determined to keep him at the Saint Mary's at all costs, are reportedly prepared to offer the fullback a new deal worth around £45,000-a-week.

But according to ESPN, Clyne is set to reject the new offer from Southampton as he looks to follow the footsteps of Luke Shaw and make a move to Old Trafford.

Manchester United boss Louis van Gaal, who is currently using Antonio Valencia as a right-back instead of Rafael, will also probably be interested in securing Clyne's signature are he has been in terrific form this season, forming a formidable partnership with Ryan Bertrand at Southampton.

Although the Red Devils have been linked to a lot of right-back including Barcelona's Dani Alves and Porto's Danilo, Clyne would be more favourable due to him having experience playing in the Premier League.

Meanwhile, van Gaal insists that United record signing Angel Di Maria will be remaining at Old Trafford next season, although he says that he will not stand in the Argentine way if he wants to leave the club.

Despite starting off his Manchester United career on a bright note, the £59.7 million signing has struggled on the pitch of late, and there have been speculations that the Argentine might leave the Red Devils after spending only a season at Old Trafford.

These rumours have been further fuelled by the fact that there was an attempted break-in at his house when he and his family were having dinner.

Many reports have suggested that the Argentine, who has reportedly put up his house on sale, will be making a move out of United at the end of the season, but van Gaal is confident that the winger will stay.

"Will he be here next season?" said Van Gaal, according to ESPN. "As a manager, you can never say no or yes because the player at the end shall always decide, but I don't think he shall move."

"Despite his incident with his wife at home, he is very pleased to be here at Manchester United."

However, the Dutchman says that he will allow Di Maria to leave if he says that he is not happy at Old Trafford,

"I'm always like that," he added. "When you see my history - that's part of my philosophy.

"A player is not just a man who kicks the ball from A to B. Also, his environment is influencing him. So, I shall always be open for that conversation, but I know also the commercial interests of the club and we have to respect that."
