Kenny Dalglish at around 30 goals in a hundred games and Denis Law at 30 with 50 odd games.
Hughie Gallagher was our most prolific with 24 goals in 20 games and the best in my time so they say was Mo Johnstone who would have scored more if he played the lesser teams but a great striker and Steve Archibald but he didn’t get a lot of game time either, can’t remember how many goals he scored mind you.
Our best striker that I’ve seen was Joe Jordan & Alan MclNally but again played very little.
Speaking of xG, Argentina is on 2.26 and 0.26 of that is Messi and he converted a chance for a goal and 2.00 is players not named Messi and they have 0 goals to show for that. So even with 8x the chances they can’t match him lol
