The playmaker had been tipped to leave the club last summer, but Real Madrid were unable to afford him. Twelve months earlier, Pogba had craved a move to Barcelona but United ruled out any prospect of selling him.
The 26-year-old has made just seven Premier League appearances all season after suffering numerous ankle issues, and he has not started a game since the 1-1 draw with Arsenal in September.
It is claimed both clubs feel that is too expensive, given Pogba's average form since he returned to United in 2016. Winning the Europa League would offer an alternative route back into the Champions League but Pogba wants to join a club where he can realistically challenge for the biggest trophies and would love the chance to play in Spain especially.More news: Body of missing hiker Stephanie Simpson found
It's certainly no surprise to see Manchester United keeping tabs on a player who could certainly help alleviate the problems caused by a Pogba departure, and if Woodward gets the £100m he wants for the Frenchman, he'll have the money for Milinković-Savić.
The transfer window will be open until later in the summer this year, however.More news: Who paid for Boris Johnson's luxury holiday?
