Manchester United must pay 60 million pounds to bring Paul Pogba back to Old Trafford from Juventus, according to The Observer.
The 21-year-old midfielder left the Red Devils for the Bianconeri in 2012 after struggling to break into the first-team, later revealing he was "disgusted" by his treatment from former United coach Sir Alex Ferguson.
The France international has been linked with Paris Saint-Germain and Real Madrid after an impressive 2013-14 campaign, earning him a place in Didier Deschamps' World Cup squad.
While new coach Louis van Gaal has seemingly earmarked Pogba as a key player to help rebuild United, it would take a British record transfer fee to do so, says the paper.
Pogba was scouted by former United boss David Moyes back in March, and Van Gaal's reported interest is an option that the player would be "open" to, reports the paper.
The Observer states that United believe that such a deal for the midfielder is both "realistic" and a "gamble": the potential fee represents Pogba's talent, age and potential, yet the constant speculation regarding his future suggests he could be a "risk buy."
Van Gaal also revealed his admiration for Chile international and Juve midfielder Arturo Vidal this week, saying: "I always wanted to buy Vidal when he was at Bayer Leverkusen but he went to Juventus."
However, the Serie A champions' general manager Beppe Marotta confirmed last week that the club was keen to hold on to its star players including Vidal and Pogba, stating: "We have clear ideas and we are a winning side, with our coach who leads the way. For this reason, I can exclude us the possibility of us selling any of our stars too.
"Real Madrid have shown their appreciation of Vidal, but no more than that. For Pogba, I hope we can sit down in the coming weeks to renew his contract."
