It doesn't look like Pogba will stay with Juventus past next summer. The French midfielder is the coveted signing every elite club wants to make and Real Madrid are also interested in his talents even with Kroos, Modric, Kovacic and Casemiro on the squad already.
Zidane wants to sign Pogba next summer, according to AS, and the manager would be willing to fight with FC Barcelona and PSG for that signing. It seems like Juventus will want to get around €100 million for his transfer, and Pogba's wages would surely be very significant knowing that Mino Raiola is his agent.
Pogba is a very good midfielder but his position and style of play is similar to Casemiro or Kovacic's. Unless Zidane decides that Pogba could play deeper in the midfield, Real Madrid don't need him right now. Either way, it definitely seems like Real could be interested in his signing, so stay tuned for more news.
