The Premier League leaders are planning to release a number of players in the summer in a bid to reduce the wage bill and Grujic is destined to depart for good. Liverpool signed Grujic in 2016 from Red Star Belgrade and was tipped to become a top player at Anfield but he failed to cement a position in the first-team. The Serbian helped Cardiff to promotion last year but has seen his performances greatly increase since his time in the Bundesliga.
"I feel very comfortable in Berlin. Hertha gave me a great opportunity to play in the Bundesliga," he said.
"I'm still pretty young, for me this time at Hertha - with the exception of injuries - has been brilliant so far to show my qualities. But, ultimately, I cannot decide. But, If I could choose myself, I would stay with Hertha for another year or maybe even two years to make a very good name for myself by improving all my qualities."
Grujic's is contracted to the Reds' until the summer of 2023 but is keen to remain at Olympiastadion Berlin.
