Team building to win UCL: Massimiliano Allegri has told Pogba to think very carefully before leaving the Old Lady, because he believes Juventus are now one of the top four teams in Europe. Two years after reaching the Champions League final, they now think they have the ability to win it, and keeping Pogba would give them an even better chance of bringing the trophy back to Turin for the first time since 1996.
Sending a message: Juventus are not a selling club. Bayern, Barcelona and Real don't accept offers for their best players; why should Juventus? Retaining Pogba and bringing in the money spent on Gonzalo Higuain through the sales of fringe players like Roberto Pereyra, Simone Zaza, Hernanes and Stefano Sturaro, though difficult, would send a strong message to the continent that Juventus are not a breeding ground for bigger clubs.
The complete midfielder: Not everyone was sure about Pogba getting the No. 10 shirt at Juventus. He is not a classic No. 10, but by the end of last season he showed himself worthy of it; 11 of his 12 assists on the season came in 2016. A complete midfielder, why would you let him go if he is willing to stay? A midfield of Pogba, Miralem Pjanic and one of Sami Khedira or Claudio Marchisio [when fit again] is one of the best around.
Cons
Missing the deal of the century: Sometimes the head has to overrule the heart; sometimes an offer is just too good to turn down. All the stars have aligned to make this the deal of the century for Juventus, and a return of more than £100m on an initial investment of £800k represents a great piece of business. No one thinking rationally would begrudge Juventus for taking it.
