Liverpool striker Roberto Firmino is a doubt for Sunday's visit of Burnley to Anfield.
The Brazilian has a thigh problem which has prevented him from training this week, and with Daniel Sturridge still unavailable Divock Origi is on standby.
Jurgen Klopp’s side has an opportunity to consolidate their position in the top four as their rivals are on FA Cup duty.
But they are also seeking to avenge an early season defeat to Burnley, Liverpool losing the second game of this campaign 2-0 at Turf Moor.
Firmino will be given a chance to recover over the next 48 hours but his absence would be significant.
Klopp is aware many remain suspicious his side's capacity to produce their best form in a less high profile fixture.
“I know what people say and it looks like this,” said Klopp.
“It is not the first time people have said something like this. We knew it after the Arsenal game these questions would be asked. We have to prove it on the pitch.
“We know how to play but in the end you have to come into specific spaces and make the right decisions. We don't concentrate only on set-pieces, counter-pressing - it is an all-around challenge.
“That is what training is for. It is a challenge. Before the Arsenal game the mood here was quite optimistic but I think a lot of people thought if we lose then we have real problems. In this moment I am not sure we will win against Burnley but I am quite optimistic because I know about the boys. No-one should expect an easy game. We are ready for the fight we will face.”
Liverpool are also still without captain Jordan Henderson who is still recovering from a foot issue.
Klopp wants the approach on and off the pitch to reflect last week’s win over Arsenal.
“You miss a chance against Arsenal and no-one is surprised. You miss a chance against Burnley and everyone thinks differently 'ah, difficult, difficult, we won't have another chance like this',” said Klopp.
“We need to feel free for playing football. We know about a few problems already but we've had good sessions and we have to go and win the game.”
