Reports coming out of Spain suggest that the Catalan giants are looking at the possibility of signing the 25-year-old superstar, who has reportedly become disillusioned with life under Jose Mourinho.
Manager Jose Mourinho has already predicted a "difficult season" if United do not do more business, so losing a World Cup-winning midfielder would only add to that.
The club's pre-season tour of the United States has hardly increased confidence in Mourinho's project.
Although the Premier League transfer window closes on Thursday afternoon, Barcelona will have until the end of the month to sign Pogba.
United are simply not interested in selling Pogba.
Guardiola keen to learn from Sarri
But, as Sarri prepares for the Community Shield against Manchester City at Wembley on Sunday, Sarri said he does not feel his new club are short-handed.
Manchester United are standing firm in their bid to hold onto star midfielder Paul Pogba after they rejected an offer from Barcelona for the France ace. The Italian club will hope that a nostalgic desire to return to Italy and the country's generous tax incentives (reportedly a factor in Cristiano Ronaldo's decision to move to Turin) could sway Pogba's decision.
They want to keep Pogba anyhow.
With Barcelona for company, The Old Lady will have to give a very convincing offer to Manchester United in order to outbid their rivals.
"It's down to the manager to get the best out of him, setting the team up and setting Pogba up in the right way to achieve the best", said the former England central defender. United have taken a stern stance in talks, insisting the World Cup victor is not for sale.
Leicester City are adamant over retaining defender Harry Maguire and have told Manchester United he is not available at any price.
Hence, according to reports, Pogba's agent, Mino Raiola had flown down to Manchester to discuss the future of his client at the club with Ed Woodward.
