Last season, City were embarrassed by League One Wigan in this competition in the fifth round and this was a game which had a similar feel from the early stages.
Swansea players were unhappy when Cameron Carter-Vickers was judged to have tripped substitute Raheem Sterling for the equaliser, while Sergio Aguero was offside when he headed in the victor two minutes from the end.
No team has ever won the quadruple of Premier League, Champions League, FA Cup and League Cup in a single season.
"Honestly I didn't watch it".
"I'm sorry it was offside. But you have to ask the authorities why the VAR is not here", Guardiola told a news conference.
"People will say not winning the Champions League is a big, big failure for this club but I don't understand when this comes from former players - they know how hard it is to win the Champions League or win the title", Guardiola said. Fans and pundits alike bemoaned the lack of VAR at the game which would have surely have denied the Sky Blues a penalty. I had until May to do whatever I could with the team and playing style, the mood.
"Sometimes it's centimetres and they spend three minutes on VAR looking at it, imagine taking the decision in one second during the game". I don't like to win in that way. The keeper was incredible.
In reality, the Citizens more than deserved the win.
But, according to the Sun, this goalscoring streak is now set to be interrupted by a spell on the sidelines, after the striker was ruled out indefinitely after a knock he sustained in the win against Paris Saint-Germain in the Champions League flared up during the 2-0 loss to Arsenal at the Emirates.
From then on in it was all Manchester City and an own goal off the back of Swansea goalkeeper Kristoffer Nordfeldt after substitute Sergio Aguero's 77th-minute penalty had come back off the post leveled the tie.
"Now we can head off for the global break and when we come back, we can try to win the three competitions we are still in".
