Liverpool have been dealt a double injury blow ahead of their FA Cup trip to Nottingham Forest
Reds boss Jurgen Klopp has confirmed that right-back Trent Alexander-Arnold will miss Reds' trip to Nottingham Forest, with Mohamed Salah still struggling to return to full fitness.
Alexander-Arnold picked up a hamstring injury against Arsenal and will withdraw from England's squad for the March break.
The setback will leave the England international a potential doubt for further Reds fixtures.
Salah, meanwhile limped off with a foot injury last weekend against Brighton and felt a recurrence against Arsenal in midweek.
"We will see, I really have no idea now," Klopp told reporters. "The analysis will follow now. I saw the Nottingham FA Cup game against Huddersfield and the deeper analysis follows after this press conference.
"Then we will make a decision about the line-up. But we have a couple of issues from the last game and before. People were ill and I hope I don't get the news that somebody is ill today. So far I didn't get that but the boys come in slightly later.
"Trent is out with hamstring so he can not be part of England as well. No good news, we will see how long that takes. Weeks, yeah.
"It's tricky, we will see how long it will take. To replace Trent is difficult but possible. We always did it. We have Milly when he is not ill anymore, we have Joe obviously, theoretically we can change system as well. We have a couple of options but he is very influential.
"But if you have a look in the past when Milly has had to step in, he did incredibly well. Incredibly well, he just has to be available and then that's fine.
"How Milly will be for Sunday, I don't know at the moment. If not, then maybe we have a very young solution which is fine as well or Joey.
"We will have a look but the way he plays, I don't know any player in the world who plays like Trent so it would be difficult to find a one to one replacement."
He continued: "Mo felt his foot again a little bit after the game so we have to see what we do with that. On top of that some other bits and bobs. We have to wait and it's always like this.
"I want to have a team at Nottingham that is fresh enough physically and mentally for the game and is really going for it. We are Premier League team number four for Nottingham in the competition, they haven't had an easy way yet but they made it. They won an important game on Wednesday against Queens Park Rangers and are close enough to think about promotion.
"Our former LFC coach is doing a proper job there. Another reason why it is a special game. If we rotate, and I really don't at the moment, it is just to have the best team possible for this specific game on the pitch."
