James Milner converted the spot-kick that set Jürgen Klopp's side on course for a victory that was confirmed when Sadio Mané added a second four minutes into added time after Aaron Wan-Bissaka's 75th-minute red card had reduced the home side to ten men. Players too. But nobody thinks about the fee now, which is good.
The Holland captain, who made eight clearances at Selhurst Park in Monday's win at Crystal Palace - five more than any of his team-mates, has kept nine clean sheets in 16 league matches since arriving.
The visitors had won on their last three visits to Selhurst Park but struggled on this occasion to open up the determined Eagles, managed by former Liverpool and England boss Roy Hodgson, in Monday's clash. "I've been in football a long time, and if that is a penalty then the game has changed beyond all recognition", Hodgson told a news conference.
"In these moments [the closing stages of the game] the fuel is really low and maybe the players need a bit of help from an angry manager - "run or I will kill you" - and they did that with a fantastic counterattack". He's trying to defend.
Liverpool thought they had scored in the 21st minute as Wayne Hennessey inadvertently threw the ball in his own net, but referee Michael Oliver gave a foul for Mane's challenge on the Wales goalkeeper, who also collided with team-mate Wan-Bissaka in mid-air.
When asked if he'd like to see it be brought in, he said: "I don't want VAR in this league because, in my opinion, this country has the best referees in the world".
With Salah sprinting clear and nearly one-on-one with goalkeeper Wayne Hennessey after being played through by Roberto Firmino, the defender risked a tackle on the edge of the area and brought the Egyptian down without winning the ball, making his dismissal inevitable. I didn't see it back so I can't say, but in the game, it looked like a penalty.
"Quality costs a specific price, with cars and with players as well, that's why we paid it. I'm more interested in the fact we played really well".
