Klopp confirms Dejan Lovren is ready to return to action against West Ham. Getty

Liverpool manager Jurgen Klopp has confirmed he will rotate his starting XI for the FA Cup fourth round match against West Ham United on 30 January, as the game comes just four days after the Reds' penalty shootout win over Stoke City in the Capital One Cup semi-final. The German also revealed that Dejan Lovren and Steven Caulker are fit to play, but ruled Philippe Coutinho, Daniel Sturridge, Martin Skrtel and Jordan Henderson. Nathaniel Clyne is also a doubt.

Klopp deployed an inexperienced line-up in the previous round against Exeter City, beating the League Two side in a replay after a 2-2 draw. Asked if he would again be turning to youth against the Hammers, he responded "Yes, but it depends on what young is in your opinion.

"It will be a different team to [the one in] the last game. We have no other chance. As I've said, [we ran] 156 kilometres [against Stoke]. We had a few players that ran 17 kilometres in this game, the highest speed ever. Nobody told them to before the game – 'Please try to break all records!'

"It was the game; we wanted to go to the final and we had to fight for it. We did it and that's great. We cannot say 'Come on, it's West Ham, it's the FA Cup, it's the world championship or whatever. And then again against Leicester City and again against the rest.' It doesn't work like that, so we have to make a few changes.

"We will make changes but only because we want to win the game – that's the only reason. When I think of the Exeter game at Anfield, it was great. It was a really great atmosphere, unbelievable, sold out, perfect."

Some changes have been forced due to injuries in the Liverpool squad. Clyne is a doubt for the match, while the game comes too early for Sturridge, Coutinho, Skrtel and Henderson, the latter of whom was taken off against Stoke due to an injury.

"Coutinho is close to returning to training but he's not in the team [yet]. He [will finish] his last two-three sessions in rehab and then he will be back on the pitch with us," Klopp said.

"[Skrtel?] no. Nathaniel, possibly, but we are not sure. He is much better, it was knee against knee and that's really painful. There's no doubt about the [durability] of Clyne. I asked him, 'One is no pain, ten is big, big pain - where are we?' and he said seven!

"Maybe you should have a rest, then. But now it's three, two, one, hopefully zero and we will see. He will train today and we will know more about this.

Speaking about his captain, Klopp added: "Hendo can be an option. He did really well for the team in a difficult time with a long-term injury. He's still having problems, it's only pain but it's always pain. We now are on a really good run but we need to use these two days and hopefully he has recovered after an intense time and is back in the race."

Klopp, meanwhile, refused to set a deadline for the long-awaited return of Sturridge, who has not played since the 2-0 defeat by Newcastle United on 6 December.

"He is still working. Sometimes it's better, sometimes it's worse. He needs consistency in sessions and that's what we try to do," he said. "There's no doubt about his quality. We have to work together on his fitness."

The manager had better news with regards to the centre-back situation, with Lovren and Caulker both fit to play.

"Dejan, it's good news. Dejan was on the bench against Stoke and is now back," the boss told reporters at Melwood," he said. "Steve Caulker is not injured but he couldn't play the last game and now he's available for the FA Cup. He's like a new player."
