One Midfielder Deal already Agreed – Liverpool Move in to Sign Another

Liverpool are already making plans for a busy summer transfer window as Jurgen Klopp looks to reinforce the quality of his squad for next season.
The Reds have already agreed the signing of one midfielder last winter in the form of Serbian international Marko Grujic. The young versatile starlet was then loaned back to Red Star Belgrade for the remainder of the season and will join the Reds in the summer (Liverpool Official Site).
Now, Daily Mail cite reports in the Polish media claiming that Liverpool have moved in and held talks to sign another midfielder in the form of Empoli star Piotr Zielinski.

As per the provided Mail link, the 21-year-old midfielder has already had discussions with Liverpool boss Jurgen Klopp over a move to Anfield.
This season, Piotr has scored 4 goals and provided 5 assists in 30 games (Transfermarkt) for the Italian club. He is a creative player in the center of the park.
Liverpool already have players like Can, Milner, Henderson, Allen, Lucas and Grujic for the midfield positions. Do they really need to sign another one in the form of Zielinski?
