Hertha Berlin coach Pal Dardai admits they'll need to wait for Liverpool midfielder Marko Grujic.

The Serb has missed the resumption of training at Hertha due to an ankle injury he suffered before Christmas.

Dardai stated, "Marko has not yet received the green light to train with us.

"He will be a topic only for the home game against Schalke (Jan 25)."

Grujic is on-loan at Hertha for the season.
