While Manchester City fans were celebrating the heroics of Willy Caballero, Liverpool fans were left questioning their side’s penalty takers.
Lucas, Phillipe Coutinho and Adam Lallana all saw their spot-kicks saved by the goalkeeper after Emre Can had cheekily converted his.
James Milner had been put down to take the fifth penalty, but City had wrapped up the shoot-out by then, winning 3-1.
But Kopites were scratching their heads, wondering why their captain Jordan Henderson or striker Daniel Sturridge were not among the five players entrusted with crucial kicks.
Jurgen Klopp didn't explain Henderson's absence from the list but revealed why Sturridge wasn’t selected to take a kick in the shoot-out.
“There was no chance for Daniel, he had cramps for the last few minutes. Everybody who was available took a penalty. We asked the players and these five players said 'yes',” said Klopp.
It’s not too much of a surprise that the former Manchester City and Chelsea man was struggling with cramp towards the end.
Sturridge has been plagued with injury during the previous two seasons and is yet to play 90 minutes this campaign - let alone 120.
However, club legend Jamie Carragher believes that Sturridge should have been taking a penalty despite his cramps and also questioned the decision to leave, arguably, their best penalty taker Milner until last.
“He [Sturridge] looks upset. He had cramps towards the end but unless he has an injury I don’t see why he hasn’t taken a penalty,” Carragher said on Sky Sports.
“I may be wrong, I don’t know about going top heavy - I don’t know why Lucas has taken the second penalty. Maybe it goes in order but sometimes you may not even get to the fifth penalty.
“You want your best penalty takers first, there’s no guarantee that everyone is going to score.”
Manchester City had led the match in normal time when Fernandinho gave the Citizens advantage when his shot somehow found it’s way under Simon Mignolet in the 49th minute.
Former Liverpool player Raheem Sterling had a glorious opportunity to seal victory but managed to steer his shot wide from just ten yards.
Sterling was left to rue his sitter when Philippe Coutinho hauled his side level with just seven minutes of normal time remaining.
Neither side really threatened in extra-time and it was left to Caballero to become the hero in the shoot-out.
Klopp’s men won’t have to wait too long to try and get their revenge with the two teams facing each other at Anfield on Wednesday in the Premier League.
