Sergio Aguero hailed Manchester City's fighting spirit after they roared back from two goals down to beat Swansea 3-2, making the FA Cup semi-finals and keeping their hopes of an unprecedented quadruple alive.
"Sometimes these comebacks happen. It is important that we've qualified for the semi-finals, so we're happy," Aguero told BT Sport.
"We always believed it would come, always we fight."
City already have the League Cup in the bag, top the Premier League and are through to the quarter-finals of the Champions League, and Saturday's win in South Wales keeps them on track for a clean sweep of trophies.
Championship side Swansea were 2-0 up shortly before the half hour through a Matt Grimes penalty and fine strike by Bersant Celina.
But Bernardo Silva pulled a goal back in the 69th minute and the visitors went for the kill, drawing level after a Sergio Aguero penalty hit a post and went in off goalkeeper Kristoffer Nordfeldt.
The City pressure intensified and Aguero had the final word in the 89th minute with a stooping header to complete a stunning fightback.
