Liverpool head coach Andoni Iraola will insist his team plays "full gas" despite growing injury worries.
Winger Victor Munoz missed Tuesday's Champions League win over Villarreal and was absent from training on Thursday as a result of a knock from last weekend.
Iraola said his participation against Brighton & Hove Albion on Sunday would be "difficult".
Munoz makes it six players now injured and while that weakens their forward options, Iraola will not accept players trying to manage their minutes during a concentrated spell of games.
"No, we cannot allow ourselves. The way we want to play you cannot play 70%," he said.
"Imagine you don't have a right-winger on the bench, I will put someone as a right-winger. I prefer to do this than you save your energy so you have to last 90 minutes.
"Give everything for 60 minutes, 65, 70, 72, then someone will do the 18, 35, whatever because we need to play full gas.
"I would like to say we are good enough to play 70% and win games but it's not. We have to play our very best because the teams we have in front of us are very good."
Iraola allayed concerns over summer signing Bradley Barcola, who also missed Thursday's training, and was optimistic midfielder Dominik Szoboszlai could return soon after going off injured at Brentford on Saturday.
"Bradley has trained today normally, he's fine, no problem. Sometimes you have to deal with the loads and sometimes they have to stay inside," he added.
"Victor has the knock he sustained at Brentford in the first half. He could finish the game very well but he is dealing with some pain since then and it was too early the other day against Villarreal and I don't know if he's going to arrive. I think it's going to be difficult but I don't really know.
"Dom is going to be out this weekend. I don't think he's far (from a return) but he hasn't trained with the group still and also considering that we started him and he had to go out, we will probably take one or two days more than we would last week.
"He's in a good place. Dom is already training outside alone and he's going to train with the group but he's not ready for this one."
