Erling Haaland scored four goals in a sensational second-half performance to help Borussia Dortmund come from a goal down to crush hosts Hertha Berlin 5-2 on Saturday and climb to second place in the Bundesliga.
It was a memorable evening for Norwegian Haaland, who notched his first away goals of the campaign and took his season tally to 10 goals in eight matches, one less than top scorer Bayern Munich's Robert Lewandowski.
It was an equally memorable match for teenager Youssoufa Moukoko, who replaced Haaland late in the game to become the youngest ever Bundesliga player at the age of 16 years and one day.
Haaland struck twice between the 47th and 49th minutes to put his team in front after Matheus Cunha had stunned the visitors with an unstoppable shot from 25 metres in the 33rd.
He completed his hat-trick when he pounced on a Hertha mistake to round the keeper and slot in, with the hosts in complete disarray.
Haaland grabbed his fourth after Raphael Guerreiro had also scored for the visitors and Hertha had briefly cut the deficit with a 79th-minute Cunha penalty.
