Jose Mourinho wants Pogba back at Old Trafford and is hopeful he can replicate his form on the global stage for United. During France's World Cup celebrations, Pogba didn't forget about his former teammate.
Arsenal manager Unai Emery is reportedly keen for the club to recruit a new winger before the end of the transfer window, but the Gunners must offload several fringe players to accommodate any further arrivals.
The Spanish transfer window closes on 31st August but the Premier League deadline is Thursday, leaving United little time to replace star man Pogba should Barcelona get their man.
Mourinho also appeared to question Pogba's focus when at his club, with prevalant outside distractions.
José Mourinho said that he would welcome any contributions made by Manchester United players who have recently returned from the World Cup.
The Portuguese is open to selling a player that he criticised for not returning to the United's pre-season tour of the United States after the birth of his second child. There is also no indication at this stage that Pogba is willing to agitate for a transfer.
If Pogba, Sanchez and Lukaku click together, United have the potential to be an exciting team going forward with Fred offering help to Nemanja Matic in the centre of midfield.
Despite the fact that United's "not for sale" stance has been widely reported, it hasn't been enough to completely kill off speculation that Pogba might still be on his way.
Mourinho's side take on Leicester on Friday in the Premier League season opener, live on Sky Sports Premier League. "He's a star", said Pogba.
According to reports in Spain, Mourinho has in fact informed Pogba that he will not allow him to leave for Barcelona.
