#4 Sergej Milinkovac-Savic
Sergej Milinkovac-Savic was a man in top demand last summer. He was set to move to top European clubs who were after him due to his performances last season. However, the Serbian's form has dipped this season and the rumours linking him to European giants has reduced in recent times.
However, if Manchester United must replace Paul Pogba in the summer, Milinkovac-Savic is a good option for the Red Devils. The Serbian can influence a game like Pogba and has the ability to be consistently involved in goals and assists. Hence, the Lazio man could definitely be a good contender to replace Pogba at United.
#3 Ivan Rakitic
The arrival of new midfielders into the Barcelona squad has reduced the game time of Ivan Rakitic this season. His playing time could be further reduced the upcoming season due to the arrival of Frenkie de Jong.
The talented Croatian is a sensible choice to replace Pogba at Manchester United. Rakitic is undoubtedly a proven performer and has experience on his side. He has the ability to control the game from the midfield and can also be creative at times. Hence, if Pogba does leave for Real Madrid, Rakitic should be a good contender to arrive at Old Trafford.
