There was to be no hangover from their Sunday celebrations; Liverpool are still very much up for the Cup.
Any of them. All of them, in fact.
After lifting their first League Cup in a decade at the weekend, Jurgen Klopp's players kept their professionalism at a sufficient level to avoid a potential Anfield upset against a much-changed Norwich City.
A superb start to 2022 now sees Klopp's side on a run of 14 games unbeaten across all four competitions.
And perhaps the key element that will be most heartening for the Reds manager is how he has utilised the full remit of his squad to do so.

Since the turn of the year, which began with a 2-2 draw with Chelsea back on January 2, Liverpool have used as many as 32 players for games in the Premier League, League Cup, FA Cup and Champions League.
The rotation has been so varied, in fact, that they have even used two managers after Pep Lijnders stood in for Klopp on the touchline at Stamford Bridge.
Or three, if you include Peter Krawietz taking charge of press conference duties while Klopp and Lijnders were self-isolating ahead of the visit from Shrewsbury Town.
So there is legitimacy to Klopp's claim that he has the strength in depth needed to compete when you consider that the only recruit to arrive in January was Luis Diaz, a player who has been a breath of fresh air since his big-money move from Porto.
The issue Liverpool would be made to confront here was just how concentrated they would be after winning their first League Cup since 2012 after 120 compelling but exhausting minutes that preceded one of the all-time thrilling final shootouts.
The antidote to that problem, however, is the squad Klopp has available to him, and he has no qualms whatsoever in using it to its fullest parameters.
So even when the attention span started to wane in the final third of this ultimately comfortable passage into the last eight, Liverpool made sure they had enough about them to avoid a punishment.
Ten changes in total were made here as Jordan Henderson was the only player to keep his place from Wembley.
Virgil van Dijk, Trent Alexander-Arnold, Mohamed Salah, Naby Keita and Fabinho were all given the evening off after their exertions in the capital on Sunday.
Divock Origi and Takumi Minamino, two players whose importance to the Carabao Cup success should not be overlooked, once more combined for the opening goal when the former played in the latter to finish high above Tim Krul just before the half-hour mark.

Minamino then rattled in a superb second before half time after being given far too much room at the back post from a corner.
The goals were just reward for the Japan international who had started the game as the brightest player in a Reds shirt.
The double took his tally to nine for the campaign and only Sadio Mane, Diogo Jota and Mohamed Salah now have more.
It's unclear what the future holds for the former Red Bull Salzburg man. Leeds were one of a few teams taking a look in January and with his former coach in Austria, Jesse Marsch, now on board at Elland Road, that interest may only intensify.
Whatever happens though he can reflect on a good season from an individual viewpoint, even if an ability to perform to the required Liverpool standard on a long-term basis may ultimately elude him.
That the 27-year-old Minamino - a player who it may justifiably be argued is the Reds' seventh-choice attacker - is closing in on double figures for the campaign only highlights the counter-claims to those who have been demanding more and more players for Klopp to stockpile in recent windows.
It was, quite probably, Minamino's best game as a Liverpool player over two years in his career on Merseyside.
Klopp was keen to play down the expectations around a possible quadruple in his Tuesday press conference and he is, of course, completely right to do so from a manager's perspective.
But as fans on the Kop sing about another Wembley visit, if the quarter-final is negotiated, the sky-high optimists may even be expecting Liverpool's odds to tumble for April's Grand National!
Klopp introduced Harvey Elliott at the break for Curtis Jones before Alex Oxlade-Chamberlain clipped the outside of the post.
Liverpool wanted a penalty when Jota's shot appeared to be handled by Ben Gibson on its way to goal as the Reds pressed and probed for a game-settling third.
The Portugal star then headed over from the excellent Elliott's cross as the teenager continued to cause untold problems for the overworked Canaries' defence.
Lukas Rupp jolted a game that was flatlining back to life when he pinged one past Alisson with about 15 minutes remaining.
Klopp sent on Sadio Mane and Luis Diaz in response to the prospect of extra time as Origi and Jota made way.
The Reds' sloppiness for the final 20 minutes or so would not in fact hurt them too much as they survived an onslaught, of sorts, from the limited visitors to move into the last eight.
The Reds just keep rolling on.
