Liverpool are leaving absolutely nothing out on the field in their pursuit of the quadruple. It is now two down, two to go, after a second cup final penalty shootout win against Chelsea this season saw Jurgen Klopp's team add the FA Cup to the Carabao Cup they lifted at Wembley three months ago. But with Mohamed Salah limping off with a groin strain after just 33 minutes and Virgil van Dijk unable to play beyond the 90th minute, time will tell as to the full cost of this victory over Thomas Tuchel's side, which saw Chelsea earn the unenviable distinction of becoming the first team in FA Cup history to lose the final in three successive seasons.

"We are mentality monsters, but there were mentality monsters in blue as well," Klopp said. "It was one penalty [between the teams]. Chelsea played outstanding, but in the end, there must be one winner and that was us today.

"I couldn't be more proud of my boys, the shift they put in, how hard they fought, the early changes."

History tends not to remember the losers, and Chelsea's failure to win again will quickly be drowned out by a red tide of Liverpool plaudits. Even if they win nothing else this season, Liverpool have already achieved a domestic cup double, a feat they last pulled off in 2001, and that year, they also won a major European trophy by beating Spanish club Alaves to win the UEFA Cup.

Klopp's remarkable team is still on course to repeat that cup treble by beating Real Madrid in the Champions League final in Paris on May 28, but before then, Liverpool could lay the platform for an unprecedented quadruple by edging out Manchester City in the race for the Premier League title. That one remains the toughest, and most unlikely, target for Liverpool to achieve. City can move six points clear with two games left to play with a win at West Ham on Sunday, but no matter the result at the London Stadium, Klopp's players will have to go to the well again at Southampton on Tuesday, needing to win to keep alive their hopes of the title.
