Liverpool boss Jurgen Klopp has described Saturday's Premier League match against Manchester United as "the biggest game I can imagine".
The Reds trail league leaders Manchester City by 18 points, with United two ahead of Liverpool , so the title race is not a genuine consideration at Old Trafford.
However, Klopp's men know a victory will take them above United into second and he said at his Friday press conference: "It's the biggest game I can imagine. I'm looking forward to it. We need to be at 100 per cent, if not even a few more (per cent)."
Asked how he would feel about his United counterpart Jose Mourinho 'parking the bus' and playing defensively, the German said: "I would never use that (phrase). I have absolutely no problem with defending. It's all about winning.
"When United attack I hope all my players are involved in defending. If someone says that is 'parking the bus', I have no problem with that."
Full-back Nathaniel Clyne is close to a return to action having not yet featured this season due to a back problem.
He may have to wait longer for his chance, though, after Klopp praised the performances of Joe Gomez and Trent Alexander-Arnold in Clyne's absence.
Fellow full-back Andy Robertson is also available while Klopp added that Jordan Henderson "looked OK yesterday" after a dead leg and Georginio Wijnaldum is "on his way back" from illness.
