Hertha Berlin GM Michael Preetz admits they want to keep hold of Liverpool midfielder Marko Grujic.

Speaking at Hertha's AGM meeting on Sunday, Preetz revealed he is in constant talks with the Reds and Jurgen Klopp regarding a possible return to Berlin for the midfielder.

"I'll keep the ball rolling and our goal is to extend the loan by one year," said Preetz.

"We have a permanent exchange with Liverpool FC and have had some personal talks with Jurgen Klopp over the past week with Marko.

"Liverpool will sit down after the Champions League final to discuss the squad for the next season and we think Marko would do well for another season in Berlin to reach the level that Liverpool play Marko himself would like to stay in.

"I can not promise anything - only that I will try everything that the boy plays next year in Berlin."
