But, speaking at his media briefing on Friday, Klopp said: “We had the problem with Martin Skrtel, a little bit re-injured. He needs another two or three weeks, we have to see.”

However, there was positive news elsewhere on the fitness front, with Sturridge, Coutinho and Origi stepping up their recoveries as planned.

The attacking trio will not be considered for Saturday’s Premier League clash at home against Sunderland but may come into contention for next Tuesday’s FA Cup replay at West Ham.

“Daniel is back in training, that’s great, since two days ago,” explained the manager. “Everything looks good in this moment. Now it is normal football training – really good for us and good for him.

Body blow: Coutinho has been out for a month with a hamstring injury

The day before yesterday he was together with Phil and Divock. If you see these three players then you know what you have missed for a few weeks.

“With Divock, Phil and Daniel in training, of course you think after five minutes maybe we should take them back into the squad.

“But that’s the moment to say ‘come on’; there are another three sessions which we can use and they are available for West Ham, that’s the idea in this moment if nothing happens in the next session.”
