Jurgen Klopp is in no doubt as far as Liverpool's top-four hopes are concerned.
To have any chance of sneaking into the final Champions League spot inside the last two weeks of the campaign, then his side must be flawless.
"Winning four games is pretty much the only chance we have but that is what we should try," Klopp said in the wake of his side's 2-0 victory over Southampton on Saturday night.
"It will be difficult but it is what we must try."
So 12 points is the target then as Liverpool aim to snatch something back from a season that has taken so much from them.
To do that, however, Klopp's men must break new ground on Thursday night.
Under him, the Reds have failed to land a telling blow on Manchester United on their travels to Old Trafford.
Liverpool are without a win in six at the home of United under their current manager, but now need to end that to have a prayer of Champions League football next season.
Klopp then must go as strong as possible and hope United's third game between Sunday and Thursday takes its toll.
Fingers will be crossed for the return to fitness of Ozan Kabak.
The Turkey international became the latest centre-back problem for Klopp when he sat out the visit of Southampton with what was described as a "minor" issue.
If fit, he starts.
Nat Phillips will continue in his place too with Trent Alexander-Arnold and Andy Robertson in their usual places at right and left-back, respectively.
Alisson Becker, who was largely excellent against the Saints, will keep his place in goal.
Midfield, as always, is the main talking point for Klopp and his staff as he weighs up his potential XI for Old Trafford.
Expect Fabinho to continue at the base of the midfield, at least.
The Brazilian has been superb all season and a big factor behind the push for the top four in the last couple of months has been his return to that defensive midfield role.
Klopp may be minded to ring the changes in the engine room, particularly given Gini Wijnaldum has played over 26000 minutes this term.

But with this one coming on Thursday after a Saturday evening fixture, Klopp might feel that is sufficient rest time for those who started against Southampton.
Wijnaldum and Thiago Alcantara will once again be pushing for a place in the side at Old Trafford as a result.
James Milner, though, was named as captain for the game that was postponed eight days ago, so he will also have his own claims to start this one.
Up top, Mohamed Salah is a nailed-on starter.
With 29 goals to his name this season, one shudders to think where Liverpool would be without the Egypt star.
Sadio Mane is pushing for a start too given his goal against the Saints.
The Senegal star has not always looked full of confidence this season but it would be a brave call to leave him out after a close-range header gave him his 14th goal of the campaign at the weekend.
So the question then is whether Roberto Firmino or Diogo Jota gets the nod to lead the line?
It was the former who was given the shirt when the team sheet dropped for the original fixture earlier this month.
But it was Jota who was selected ahead of the Brazilian on Saturday night.
There is little debate over whose output has been the most productive in front of goal, however.
Jota, even with a three-month injury lay-off to contend with, has scored twice as many as his team-mate in his maiden campaign at Anfield.
But while Firmino's tally of six is half that of Jota's, his eight assists comfortably dwarf the one that Jota has laid on.
It is this call that represents Klopp's biggest as thoughts drift towards Thursday's big match at Old Trafford.
