Jurgen Klopp has revealed his captain, Jordan Henderson still has a heel problem and is playing through pain.
The England international missed three games due to the injury, but has played in the matches against United and Swansea.
However, Henderson is still contending with discomfort as Liverpool closely manage the problem.
Asked if it was similar to the heel issue Henderson struggled with last season, Klopp said: “It is different – similar but still different. We know much more from last year about it.
“We don’t train a lot in this period between the games so instead of running one day, when the players who have played 90 minutes are running for recovery, he is on the bike – that is maybe the only difference with what we do with him.
“The rest is how I said – you don’t use the phrase ‘bite on his teeth’ [grit his teeth]?
“You know what it means, it is not the moment to feel nothing, he always feels a little bit, but he can cope with it.”
