The 19-year-old midfielder arrives from Crvena Zvezda after impressing with the Serbian club, drawing comparisons with Liverpool legend Steven Gerrard.
An Under-20 World Cup winner during the summer of 2015, Grujic has scored five goals and registered seven assists in 21 games for Red Star this season, as they storm to the Serbian SuperLiga title.
However, Grujic will not be playing for Liverpool until next season, with part of the transfer confirming that the youngster will return to Red Star on loan until the end of the season.
This is a decision which has not pleased Liverpool fans, especially as the Merseyside club are currently suffering in the midst of an injury crisis, and have few players available.
Jurgen Klopp could realistically have called upon Grujic for the second half of this season, knowing that the youngster is a player who fits his high pressing system and is currently in fantastic form.
Following the confirmation of the transfer, and Grujic’s loan return to Red Star, Liverpool fans took to Twitter to share their thoughts on the deal, with many questioning the club’s decision to not use him this season.
Gutted Grujic is going back on loan.. Would've liked to see him play #LFC— Hendo (@HendoCan) January 6, 2016
Don't understand why #LFC won't keep Marko Grujic instead of sending him back on loan. Oh well.— Kyle (@Mohoroski6) January 6, 2016
I would like to think the club tried Grujic at CB in training before finally agreeing to loan him back to Red Star. https://t.co/fZjuk8gh17— Nick Sculley (@sculls_6) January 6, 2016
It's annoying that Grujic is going back out on loan #LFC— Ryan Cuthbertson (@Ryancuthbrtson) January 6, 2016
@lfc sign Marko Grujic from Red Star Belgrade and loan him straight back. Explain? we have more top fit players on loan than in the squad.— Browny (@Browny_K) January 6, 2016
Grujic on loan back to RedStar to the end of the season. #lfc I dont like this after the Origi deal...— My Liverpool FC (@My_Liverpool_FC) January 6, 2016
Welcome Marko Grujic! Shame he's off back on loan though, surely an extra million would have sorted that?— Martin Turner (@Turner_LFC) January 6, 2016
