#1 Toni Kroos
Although Toni Kroos has been one of the best midfielders in the world for the last few seasons, his performance in the present campaign has not been up to the mark. The German has failed to make an impact in most of the games that he has played for Real Madrid this season and this has, in turn, affected the Spanish giants in La Liga and the Champions League.
Kroos has been linked with Manchester United in the past and with Real Madrid looking for some fresh faces in the midfield, it could be a perfect opportunity for the Old Trafford club to attract the German to Manchester United.
Kroos is a classy footballer and it will not be long before he returns back to form. United has missed someone calm and composed in the field who can also play creatively, and Toni Kroos can fulfil this very easily. If Pogba does leave the club, Kroos must be the first in line to sign for Manchester United.
