What a nasty, nasty question OP
Albertz is my all time favourite player so Der Hammer for me.
They were terrified of him like I've never seen them terrified of any player.
Literally every time he had the ball in the opponents half, it was a potential goal. Every free kick was a potential goal.
Add to that that he was so strong, so so strong. If he picked the ball up in the centre circle and wanted to drive into the opponents box, he could do it and there was nothing bar a foul anyone could do about it. That's actually my only criticism of big Jorg, that he never done that even more often than he did.
An Albertz today is a 50m player, easy. We've never, ever replaced what he gave us. We had many shit hot players in Gazzas position in later years, but nobody ever gave us what he did.
That's not me saying Albertz was a better player than Gazza by the way, but there's a very strong case for saying Albertz contributed more to Rangers in many, many ways
