#2 Douglas Costa (from Juventus to Manchester United)
Juventus have probably one of the strongest squad in Europe right now. Their team is full of world class players who are ready to execute any of tasks Massimiliano Allegri demands of them.
Just look at the attackers they have on their disposal: Mario Mandžukić, Paulo Dybala, Cristiano Ronaldo, Juan Cuadrado, Federico Bernadeschi and Douglas Costa. It's obvious that there is no space for all these players. And, the first player that could leave the club because of his limited playing time is the Brazilian, Douglas Costa.
He could be on his way to Manchester United who are ready to pay €60 million for him. The Red Devils are desperate to get a world class right winger. This summer, they wanted Ivan Perišić but they couldn't get him. With Cristiano Ronaldo's arrival at the club, Costa fell behind in the pecking order, so it's realistic to expect him to leave the club.
