Liverpool manager Jurgen Klopp says Adam Lallana is an injury doubt ahead of today's early kick-off at Norwich City.
The 27-year-old picked up the injury during last week's defeat against Manchester United and will take a late fitness test to understand if he is fit to start against the Canaries.
The German also revealed that striker Daniel Sturridge will miss another ten days as he continues his struggle for fitness.
"At the moment there are no new big problems but could be big enough that we have to change a few things," Klopp explained.
"Adam Lallana is a little bit in doubt. He's here and trained yesterday, but not normal training. He had a little issue but we have to see, we have to wait until training today to see.
"It was a little bit of a muscle [problem] only in the Manchester United game. Afterwards he needed a little bit longer to recover and now we have to see if we have enough time to bring him back.
"I think that's the only new one. From the others, no players are back.
"[Daniel Sturridge?] The last four days were really good and he could do what he had to do. In this moment he is in a good way, but still needs time. I can't change it.
"So there's nothing really new in this situation – it is training. But, to be honest, the last four days were good and hopefully he can do it like this for the next four or five days and then it will have been 10 days, which is better than only two.
"Then we have to see where he is and how the situation is, and we can hopefully decide if it's time for him.
"To have a player like Daniel in your squad is always a good situation. When it's not possible to use him, it's not a good situation.
"We have enough games this season when we hopefully can use him, but not, if nothing happens, for at least the next 10 days."
