Haaland has set the world alight since moving to Germany and already looks a bargain, while his former RB Salzburg team-mate Takumi Minamino has had a slow start to life at Anfield.
That saw Klopp asked about the two's contrasting starts to life at their new clubs, but the German was adamant both have made the right choice.
“The difference couldn't be bigger," he said.
Erling Haaland made a perfect choice with Dortmund, and Taki made a perfect choice too.
“Dortmund needed a striker. Everybody blames Man United for not getting him, but we wouldn't have got him - not that we tried. It's as easy as that.
“He wanted a top team, as soon as possible, with an open space - Borussia Dortmund.
“That's timing. I hope you know how much I love and respect the people at Dortmund, but it's not that they made a perfect approach and did this and that, it was more they were there, had the space, number nine… 'Here we go, you are 19 years old, want to play Champions League, top end of Bundesliga, so go for it'.
“Nobody else had a chance, I'm pretty sure, no matter what they say."
