Paul Pogba's agent Mino Raiola reportedly has an agreement in principle with Barcelona regarding the Frenchman.

According to Rai Sport (h/t Calciomercato.com), Raiola and Barca have come to the agreement despite Manchester United being adamant their star will not be sold.

What's more, it's said Barcelona midfielder Arturo Vidal has been urging manager Ernesto Valverde to do his utmost to recruit his former Juventus team-mate.

Raiola hinted at the idea of Pogba leaving United back in August when he responded to criticism of the Frenchman by club legend Paul Scholes:

Pogba has struggled to justify the then-world record £89 million fee the Red Devils paid to bring him back from Juve in 2016.

The 25-year-old helped United win the UEFA Europa League and EFL Cup in his first season back at Old Trafford, while last year they finished second in the Premier League and reached the FA Cup final, but he has only shown his ability in patches.

Pogba offered a timely reminder of what he can do when on form at the 2018 FIFA World Cup, though, in which he played a key role in France's success.

Barca would need him to consistently perform at that level to justify his purchase, but as the Telegraph's Sam Wallace and ESPN's Mark Ogden noted, the Catalan giants have neither the resources nor the space to sign him or incorporate him into their current setup:

Unless the Blaugrana sell one of their top earners for a large fee, it seems they simply wouldn't be able to afford him at this moment in time, particularly as United's reluctance to part with him would drive any potential transfer fee up further.

Raiola may have an agreement in principle with them, but unless they can back it up in reality, the move is a non-starter.
