Willy Caballero was the hero on Sunday, saving three spot-kicks to hand Manchester City the League Cup.
So, when the Argentine was dropped to the bench for the Premier League clash against Liverpool it was always going to be a talking point.
Obviously, Joe Hart is the Citizen’s best goalkeeper and was always going to be given the nod in a crucial league clash against Jurgen Klopp’s men.
But in the first-half against the Reds he allowed a tame Adam Lallana shot to find the bottom corner.
Lallana drove forward an unleashed a pee-roller with his left foot which didn’t look like it would trouble England’s number one.
But Hart failed to move his feet quick enough and Lallana’s shot trickled in the back of the net.
Watch the goal here:
Twitter was, as always, far from sympathetic towards Hart and pointed the finger at the 28-year-old.
Things got even worse for Hart and his side as former City midfielder James Milner beat him just a few minutes later.
It could be a crucial mistake by the stopper as his side look to get themselves back into the title race. They started the day in fourth, ten points behind league leader Leicester but with two matches in hand.
However, if they lose against Jurgen Klopp's side on Wednesday, it would make it incredibly difficult for them to lift their third Premier League trophy in five seasons.
Just a couple of weeks ago, City were eying up a quadruple as they looked to give departing manager Manuel Pellegrini the perfect send off.
However, those dreams ended when an under-strength side were thrashed 5-1 by Chelsea in the FA Cup.
They may have beaten Liverpool in the Capital One Cup final on Sunday, giving them their first trophy of the season, but if they leave Merseyside empty handed on Wednesday they could have to settle with the thought of the double.
City have one foot in the Champions League last-eight after beating Dinamo Kiev 3-1 away from home as they go in search of their first ever European triumph.
Wednesday's opponents Liverpool have very little to play for in the league with no realistic chance of qualifying for a top four finish. However, they will be thoroughly enjoying dishing out some revenge to the side that caused them heartbreak on Sunday. That's if they can keep hold of their 2-0 lead in the second-half.
If City do fail to win, it will continue their retched run at Anfield. Before tonight's match they had failed to win on their previous 13 visits to the red side of Merseyside.
