As Liverpool know, the difference can be the goalkeeper. Adrian has previously proved to be an able deputy for the injured Alisson but he was sadly at fault as Atletico Madrid scored the precious extra-time goals that meant Liverpool will be champions of Europe for not much longer.
At the other end of the pitch stood Jan Oblak, who can lay claim with Alisson to the right to be called the world’s best goalkeeper, and although he was beaten twice he produced save after stunning save to deny wave after relentless wave of Liverpool attacks.
Having been beaten in normal time by Georginio Wijnaldum, Oblak was beaten early in extra-time by Roberto Firmino as he scored his first goal at Anfield in almost a year by volleying home after his header had rebounded back off the post.
It appeared that would send Liverpool into the quarter-finals but, incredibly, Atletico struck back with two goals by substitute Marcos Llorente in eight minutes as the Spaniards showed incredible reserves of resilience to go through.
