Jurgen Klopp won’t have to look too far for positive omens as Liverpool get set to host Real Madrid on Wednesday.
It was on this day five years ago when his reign really started to gather pace when he witnessed Anfield’s true power first hand.
A Europa League quarter-final tie may not have the immediate resonance of some of the more celebrated continental triumphs, but their comeback against Borussia Dortmund is a key chapter in the Klopp story on Merseyside.
It was April 14 2016 when the Reds headed into the game against the German’s former side, with the tie finely poised from their 1-1 draw at Westfalenstadion in the first leg.
Liverpool, though, would quickly find themselves in need of an unlikely comeback.
Inside 10 minutes of the second leg, the Reds would be two goals down as strikes from Henrikh Mkhitaryan and Pierre-Emerick Aubameyang left them facing an uphill battle.
Thomas Tuchel’s BVB had shown why they were considered Europa League favourites during an impressive first-half performance that dizzied their hosts.
The Reds’ prospects of a revival appeared slim at the break.
To the Liverpool manager’s credit, it was his knowledge of the history of the club he was in charge of that helped his players turn the tide after the break.
Klopp urged his charges to remember the 2005 Champions League final when Rafa Benitez’s men overturned a 3-0 deficit to a vaunted AC Milan side to win their fifth European Cup in Istanbul.
“At half time, the atmosphere was good. I was satisfied with the game. Not with the goals, but with the game in general,” Klopp said.
“I told the lads this; a few older Liverpool players who now work as television experts played in a game where they were 3-0 down at half time in a Champions League final.
“So even when it is not really likely, it is possible. And we should try to go for it.”
And go for it they did.
Divock Origi gave them a shot in the arm three minutes into the second half, but Klopp’s men were dealt another blow when Marco Reus slotted home shortly before the hour mark.
Liverpool headed into the final half hour trailing 4-2 on aggregate and needing three to go through to the last four of Europe’s secondary competition.
Philippe Coutinho conjured up a moment of magic, as he so often did during his five years at Anfield, before Mamadou Sakho gave them real hope on 77 minutes.
It was left to Sakho’s centre-back partner, Dejan Lovren, to produce the all-important fourth as he converted James Milner’s cross at the back post to complete the turnaround in stoppage time.
The post-match celebrations will live long in the memory.
