Liverpool boss Jurgen Klopp admits he's long been a fan of Erling Haaland.
The Reds host Haaland and Manchester City on Sunday.
Klopp said, "When he was very young, you could see the potential, it was insane.
"I don't think he started against us (Borussia Dortmund) in a home game, I think he was injured or came on - but we were already pretty busy with thinking about him, I can remember that.
"How can you close him down, shut him down - he scored anyway!
"Physically he sets new standards, the combination of being really physical and technical and sensational awareness, his orientation on the pitch is exceptional, he knows always where the decisive gaps are, barely offside.
"Now at City he has some of the best players in the world at setting up goals - De Bruyne, Mahrez, Foden, Bernardo Silva, - so it's a perfect fit."
