Milner Liverpool: Four signings Reds still need in midfield, including £37m Gerrard replacement & Brazil international

4) Radja Nainggolan (AS Roma)

An out-and-out defensive midfield player, Radja Nainggolan is another Roma player linked with Liverpool in recent times after some fine displays in the middle of the park at the Stadio Olimpico. A powerful player with great work rate, Nainggolan could complement the play of Jordan Henderson, Milner and Pjanic well if he is also brought into the club, offering more protection to the back four.
