You do not have to flick far through the book of football cliches to find "After the Lord Mayor's Show". It is the clear and present danger for Leeds United at Elland Road on Saturday.
Every seasoned football fan knows it well, the on-field comedown after a high. Leeds have hit two historic ones in their last two games.
Now they are at home to the bottom side in the league, Wolverhampton Wanderers.
Doomed to relegation they may be – it could be confirmed as soon as Sunday – but Wolves have shown a fair amount of fight since Christmas, winning only two fewer points than Leeds in that time, so home manager Daniel Farke has been demanding "super-, super-professionalism".
But nights like Monday and evenings like the one eight days earlier only come around every four decades or so, so not enjoying them would make what the Whites achieved pretty pointless.
"We are on a really good path when I compare us with the situation I found nearly three years ago," says Farke, manager since 2023.
"Back in the top flight, (in an FA Cup) semi-final for the first time in such a long time (39 years), many highlights during the season... but I don't want to celebrate too much.

"I want to stay focused and concentrated right now on this run-in. We also want to keep going as far as possible in the FA Cup."
Leeds are breaking the back of their relegation battle, but not quite there yet. To reach an FA Cup semi-final and enjoy a historic Old Trafford win, as well as beating club world champions Chelsea this season, and drawing twice with English champions Liverpool yet still get relegated would be more bitter than sweet.
Leeds are currently six points ahead of Tottenham Hotspur with six to play. Given they go to Spurs in May, a few more yet would be handy. Leeds play four teams below them in those six games, but that comes with no guarantees.
"We want to make sure that we deserve to play at Premier League level next season," sys Farke. "I expect that we need to win a few more points in order to do this.

"I'm not in the mood to speak too much about what will be in the mid- and long-term. We can do this after everything is achieved.
"But at the moment I can't really waste one per cent of my energy and look too far ahead of just the next game to make sure that we also win the next points."
But that did not stop them celebrating Monday. To quote one of Farke's predecessors, Neil Warnock, the mantra was "Enjoy it by being disciplined."
"If you don't enjoy moments like this, a first win in more than 40 years, then you're like a candle at some point," argues Farke. "You're burned out and you ask yourself one day, 'Why am I doing all this disciplined work?'

"My mantra is always to stay focused, to be disciplined.
"I demand a lot from our players in all aspects – with their focus, with their concentration, with their workload and training, with their physical output, with their nutrition. I want them to be super-, super-professional.
"But there must also sometimes be a moment or a day when you can allow yourself to enjoy it a little bit.
"This doesn't mean that you do something crazy and go for a night out and celebrate for two days. You can't afford this when you have another important game five days later.
"No one was out in the bar drinking after the game or indisciplined with nutrition but you can still feel the joy and still joke a little bit and enjoy this.
"My players know that I want them to work harder than probably many other teams in this league because we have to do this. We don't have the best individual quality in this league.

"But they also know when there is a chance to reward them with something like this, I will always do this in a mindful way. They know that they will be rewarded whenever there is a chance.
"During this week with this quick turnaround, Monday, Saturday, the next game is Wednesday, the next game is Sunday, it's a crucial point.
"We can still smile, we can still enjoy being together on the training pitch but it doesn't take anything away at the moment.
"We have to be super-disciplined and super-focused in everything we do."
It starts with beating the worst team in the league on Saturday.
