Lack of VAR at Swansea surprises Guardiola after controversial Man City comeback

Manchester City and Watford reach FA Cup semi-finals

In reality, the Citizens more than deserved the win.

City had levelled in contentious circumstances too when Cameron Carter-Vickers was judged to have tripped replacement Raheem Sterling in the area and Aguero's penalty hit the post before rebounding in off Nordfeldt for an own goal.

The Liberty Stadium is equipped for VAR but because other Championship grounds are not, it was not operated for the sake of consistency.

"If it is not penalty, and it is offside like the people say, I'm sorry", Guardiola said.

"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.

Aguero then completed the turnaround at the end with a header despite appearing to stray offside and, had VAR been in use, their second and third goals arguably would have been disallowed.

"They ask all the clubs about the VAR (video assistant referee) and all around Europe the VAR is there and here it's not".

"That seems a bit odd considering we were there for seven years and all the technology is placed here to accommodate it".

The VAR row overshadowed an excellent Swansea display which saw Graham Potter's side take a 2-0 half-time lead through Matt Grimes' penalty and a superb strike from former City player Bersant Celina.

Pep Guardiola's team roared back from a two-goal half-time deficit to score three times after the break, with Sergio Aguero grabbing a disputed late victor in a 3-2 victory.

Guardiola said: "You have to say congratulations to Swansea, it was incredible".

"But we didn't give up".

"I want to congratulate the team and everybody. The performance was one to be very proud of". "It's not nice but thankfully nothing happened this time".
