Arsenal's miraculous mass recovery ought to be manna from heaven for producers of the energy drink that sponsors this competition.
Unable to field a team on Sunday to virtually full strength on Thursday, offering Carabao a hint of some kind of magic potion akin to the elixir of life.
Somewhere across North London Antonio Conte would have raised a wry smile.
Arsenal could not play on Sunday but Mikel Arteta named a strong line-up to play Liverpool

Maybe Jurgen Klopp did too once his team had booked into next month's Wembley final against Chelsea.
Mikel Arteta was able to select his first choice goalkeeper and back four, the bedrock upon which so much of Arsenal's impressive development this season has rested.
Up front, captain Alex Lacazette supported by the youthful exuberance of Bukayo Saka, Gabriel Martinelli and Emile Smith Rowe, who was starting his first game since the quarter final against Sunderland.
Only in midfield, were Arsenal depleted, with Mohamed Elneny on international duty at the Africa Cup of Nations and Granit Xhaka serving the first of his two-match ban for the red card at Anfield, last week.

Arteta deployed Martin Odegaard deeper than usual alongside Sambi Lokonga, while Thomas Partey was named among the substitutes, having played for Ghana on Tuesday and touched down in London at midday yesterday, less than eight hours before kick-off.
Having left the equatorial climes of Cameroon behind, Partey sat on the bench swaddled in multiple layers clothing as temperatures dipped towards zero, until summoned in the closing stages.
His involvement may say something about the spirit evolving at Arsenal. Proof that, while Arteta is in the habit of ostracising elements of his squad, those who are on board with the project, as he likes to call it, are firmly on board.
These players represent his trusted core, and on their day they can give the best teams a game but this was not their day.
Jota was the man of the match and the difference maker for Jurgen Klopp's side
