The France international has been linked with a potential switch to Manchester United over the past week or so following Zinedine Zidane’s return to Real Madrid.
The 26-year-old has been in excellent form for Ole Gunnar Solskjaer since the interim manager replaced Jose Mourinho at Manchester United back in December.
Manchester United will be loathe to lose their club-record signing to Real Madrid given that Ed Woodward is looking to provide the next permanent manager with the tools to succeed.
Pogba still has two and a half seasons left to run on his current deal at Manchester United, so talks over a new deal could be on the horizon in the near future.
A move to Real Madrid would present Pogba with a better chance of winning the Champions League on a regular basis given the club’s recent dominance of the competition.
And Daily Record reporter Castles believes that the most likely outcome is Pogba committing to a new long-term contract at Manchester United on improved terms.
“It will be hard for Pogba to get to Real Madrid because of the costs of him as a player,” Castles told the Transfer Window podcast.
“He is on a top salary at Man United. He was the world-record transfer when Man United signed him. Ed Woodward made it clear how important Pogba was to him when he was in conflict with the previous manager.
“There is no doubt Pogba would like to move elsewhere if he can get himself a better club with more chance of winning domestic and Champions League titles.
“The realistic outcome, if he can get any serious interest, would be to improve his contract.”
Manchester United sold Pogba to Juventus in an £800,000 deal in the 2012 summer transfer window under Sir Alex Ferguson.
The Red Devils re-signed Pogba in an £89m deal from Juventus in 2016 after Jose Mourinho’s appointment.
