The Midfielder, who is under contract at Red Star until 2018, has been linked with a number of top European teams recently with Chelsea amongst those after his services.
Grujić, is widely regarded as one of Red Star’s most influential players despite him just being 19 years old and he has expressed his intent to play for Chelsea one day.
Grujić said: “I never doubted my decision to stay at Red Star. This choice could help my future growth, when I move abroad one day. It was difficult to refuse a very tempting offer when things here at Red Star were going badly, but now things have improved. I hope one day to play at Chelsea or Barcelona, but not immediately.”
Grujic has been likened to current Chelsea midfielder and compatriot Nemanja Matic.
Grujić has featured quite regularly for Red Star this season and has scored four goals in 16 league appearances so far.
Chelsea, have endured an abysmal start to the season, and the Blues welcome Norwich to Stamford Bridge in what is sure to be a tightly contested affair as Mourinho would be eager to get back to winning ways following his stadium ban which made him unable to feature in their last game against Stoke.
