The OP's suggestion of little Luis' goal v Juve is my Liverpool goal of all time.
Why? I'm 45. So I remember all the glory, glory years of LFC as top dogs. Then we declined. And had bit part status until the early 2000s when we showed signs of stirring, then fell back again. Rafa came in, we had a totally average squad (for LFC). Nothing much was expected of that first Rafa season. Owen had gone, a rebuilding job was on the cards. We got past the group stage and made some progress - last ditch in the case of Olympiakios - and then got Juve. They were stronger than they are today. We were average. I fully expected to go out at that stage. Thinking 'decent first attempt for Rafa.' Then Sami scored a beaut of a goal and you just thought 'Maybe, maybe..' Then came a world-class lob by Luis and suddenly we were back somewhere I couldn't remember being for a long, long time.
The goal that brought us back to life.
