Huh? Haaland has been reliably above goal per game in the Champions League ever since playing for the Austrian minnows Salzburg as a teenager. In fact scored a hat trick in his very first Champions League match followed by four more goals in the three following fixtures, all against Liverpool and Napoli against whom Salzburg were very much
not stacked. That's what got him the transfer to Dortmund and ultimately Manchester City after he had repeated the same in Germany for three years and now also in the Premier League. Current age 22. Just so for comparison, Lionel Messi and Cristiano Ronaldo
put together had 33 Champions League goals in 78 games at that age. Haaland has 35 in 30.
Besides even those tap-ins are frequently completely ridiculous.
