Jurgen Klopp plays waiting game on Daniel Sturridge

Liverpool manager Jurgen Klopp admits he does not know when striker Daniel Sturridge will be fit to return.

The England international has not played since November 19 because of a calf problem and his manager has already ruled him out of their next two matches against West Ham, this weekend, and Middlesbrough.

Even then, Klopp will put no timescale on when the 27-year-old will be ready to come back — which is an issue considering Danny Ings has been ruled out for the rest of the season with knee ligament damage and Philippe Coutinho is out until the new year with an ankle injury.
