Last night, Liverpool did the unthinkable as they defeated Barcelona by 4-0 to advance to the Champions League final.
Klopp’s men had to overturn a three-goal deficit at Anfield without two of their key players in Roberto Firmino and Mo Salah but completed the most remarkable of turn arounds thanks to a double from Divock Origi and Gini Wijnaldum.
The game was filled with drama and intrigue as the Reds overcame incredible odds to put Messi and co to the sword at Anfield.
Here Pundit Arena takes a look back at six of the most mental games in Champions League history.
Liverpool 4-0 Barcelona (2019 Champions League Semi Final Second-Leg)
Klopp’s men, knowing they needed at least three goals on the night, started in incredibly bright fashion as Divock Origi gave them the lead, tapping home after Jordan Henderson’s shot was saved by Andre Ter Stegen.
The home side pushed for another goal as Barcelona began to settle into the game keeping the deficit to two goals as the first half came to a close.
Ten minutes into the second half Gini Wijnaldum grabbed their second with a sweet strike from the edge of the area before quickly levelling the tie rising above the Barcelona defence to head past Ter Stegen as Anfield came unglued.
After a conservative 20 minutes, Liverpool took the lead in incredible circumstances, as some quick thinking from Trent Alexander-Arnold found Origi in the box for his second and the Reds’ fourth.
Liverpool held on to complete the most remarkable of comebacks.
Manchester City 4-3 Tottenham (2019 Champions League Quarter Final Second-Leg)
Spurs had a slender 1-0 lead going into Wednesday night’s second leg at the Etihad and knew that if they scored just one away goal then City would require three to go through. Essentially, both sides knew they needed to come out of the blocks hot.
What followed was arguably the craziest opening ten minutes in Champions League history as the first four shots of the game all found the net, with Raheem Sterling grabbing the first and Bernardo Silva the last in between a brace from Son Heung-Min.
City then went ahead through Sterling again ten minutes later as the first 21 minutes saw five goals scored. The second half may have had fewer goals but it had arguably more drama.
Guardiola’s men grabbed their fourth in the 60th minute and knew that all they had to do was hold on to qualify for the last four and keep their treble hopes alive.
Spurs found the perfect response through Fernando Llorente, and despite the decision going to VAR, the goal stood.
City pushed and pushed and thought they had found the most dramatic of late winners as Raheem Sterling netted his hattrick only for VAR to again intervene and chalk off the goal amidst wild City celebrations.
Chelsea 4-4 Liverpool (2009 Champions League Quarter-Final Second Leg)
Another Champions League quarter-final involving two English sides, Liverpool and Chelsea put on a goal fest in their second leg at Stamford Bridge.
Chelsea had a stellar 3-1 lead going into the second game but Fabio Aurelio’s cheeky free-kick and Xabi Alonso’s second saw Liverpool right back in it after 30 minutes.
Two goals in six minutes after the break from Alex and Didier Drogba levelled it on the night before Lampard stepped up to put them 3-2 up at Stamford Bridge and 6-3 up on aggregate.
The tie looked over as the game entered the 80th minute only for Lucas and Dirk Kuyt’s two goals in three minutes to get Liverpool back into it and within one goal of a spot in the last four.
Lampard struck the final blow however scoring another as Chelsea advanced 7-5 on aggregate in a crazy game.
Barcelona 6-1 PSG (2017 Champions League Last 16 Second-Leg)
An almost immeasurable comeback from two years ago as Barcelona overcame an astonishing 4-0 first leg defeat against PSG to book their place in the last eight.
In the 88th minute of the game, Barca found themselves 3-1 up on the night but still 5-3 down on aggregate as despite their impressive performance the tie looked beyond them.
Brazilian striker Neymar then struck twice late as Barca began to believe that the most remarkable comeback in Champions League history (sorry Liverpool) could be possible.
In the 95th minute, the ball fell to Sergi Roberto in the box who found the back of the net to send the Nou Camp into ecstasy.
Liverpool 3-3 AC Milan (2005 Champions League Final)
Perhaps the most iconic final the competition has ever seen, 2005 in Istanbul will forever be remembered as one of the finest days in Liverpool’s history.
Up against an AC Milan side blessed with the likes of Andriy Shevchenko, Paolo Maldini and Andrea Pirlo, Liverpool found themselves up against it early as Maldini opened the scoring in the first minute.
A Hernan Crespo brace had Milan 3-0 up at half-time as it looked as though the Italians would prove far too strong for their Premier League rivals.
What followed was one of the most spectacular comebacks of all time as, led by their talismanic captain Steven Gerrard, Liverpool clawed their way back into the game with goals from Gerrard, Smicer and Alonso drawing them level after 90 minutes.
A penalty shoot-out followed with keeper Jerzy Dudek proving the hero as he saved Shevchenko’s spot-kick to hand Rafa Benitez’s side the trophy in Istanbul.
Manchester United 2-1 Bayern Munich (1999 Champions League Final)
A game that will be remembered for the last couple of minutes alone, Manchester United’s Champions League triumph in Barcelona in 1999 was truly remarkable.
1-0 down to Bayern Munich for the majority of the game, United grabbed a late equaliser through Teddy Sheringham in the 91st minute and looked as though they had done enough to take the game into extra time.
Just moments later super-sub Ole Gunnar Solskjaer snatched victory at the death as Manchester United completed an amazing late comeback and secured the treble.
