Liverpool manager Jurgen Klopp has confirmed Reds striker Daniel Sturridge faces another stint on the sidelines after picking up a hamstring injury in the 2-0 loss to Newcastle United on Sunday.

Klopp was eager to stress the injury was 'not that serious', but said the club would focus on building up Sturridge's 'resistance' before the 26-year-old returns to matchday action.

"It's a hamstring and it's not easy to say when he can be back for us," Klopp said.

"There are two different things we have to look at – the one thing is the injury and the other is how we can bring him into a shape that is not so intensive for him, so he needs to train.

"The good thing with the muscle injury is that early [on] he can start to run and to train - not football but all the other things he needs. If you look at his history in the last months, and maybe the last year, it's not a long time he's been able to train.

"With all the games [we have], we have to find the specific point when it's possible to bring him [on] for minutes and what makes most sense for his general shape.

"I can't say at this moment what we will do exactly, but we'll have to look at it.

"The injury is not that serious. The last time he trained, he got 60 minutes at Southampton, which was quite good, and then another 30 at Newcastle, which was not that good because in one of the first moments when he had a shot at goal, he felt something in the muscle.

"It's not that serious, but it's not possible to play. Now we have to build up his resistance. It is like it is. We have to help him be more resistant for all the games we have."
