Rangers great Ally McCoist was impressed by Alisson's winner for Liverpool at West Brom yesterday.
The former Scotland striker admits he was in awe of the goalkeeper's header.
He told talkSPORT: "(Manager Jurgen) Klopp said insane technique, that's about right. It was slightly behind him and I think Klopp is 100 per cent calling it insane technique, but I don't think he really did it justice.
“He said it was glanced, and it did to a certain degree, but it was glanced with power as well into the far corner.
“It was genuinely a centre-forward's header, and I mean an old fashioned one, like somebody getting above a defender and directing it towards goal.
“It was a tremendous goal, it really was."
