Liverpool vs Sunderland: Daniel Sturridge, Philippe Coutinho and Divock Origi remain out

Liverpool manager Jurgen Klopp has confirmed Daniel Sturridge, Philippe Coutinho and Divock Origi will remain on the sidelines for the Premier League game against Sunderland on 6 February but could be ready to play in FA Cup replay at West Ham United on 9 February. The German boss, meanwhile, revealed Martin Skrtel will be out of action for another two or three weeks after the centre-back suffered a setback in his recovery.

Sturridge, Coutinho and Origi returned to training earlier in February after a long spell on the sidelines. But Klopp admitted the Sunderland game will come too soon for them because he does not want to take any risks with the trio.

Former Chelsea and Manchester City striker Sturridge has struggled with injuries over the past year, with him last featuring in the 2-0 defeat to Newcastle United on 6 December 2015. Coutinho, meanwhile, has been out of action since the first leg of the Capital One Cup semi-final against Stoke City, where he limped off with a hamstring problem.

"Daniel is back in training, that's great, since two days ago," Klopp said. "Everything looks good in this moment. Now it is normal football training – really good for us and good for him.

"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."

Klopp, meanwhile, claimed earlier in February that Skrtel was also expected to return to training following more than a month out, having being on the sidelines since the defeat to Watford on 20 December 2015. The Liverpool manager said: "We had the problem with Martin Skrtel, a little bit re-injured. He needs another two or three weeks, we have to see."
