Teenager Erling Haaland announced himself on the European stage with a stunning first-half Champions League hat-trick as Red Bull Salzburg thrashed Genk 6-2.
The 19-year-old, son of ex-Manchester City and Leeds United defender Alf Inge Haaland, became only the eighth player to score three times on debut in Europe's elite competition.
Hwang Hee-chan, Dominik Szoboszlai and Andreas Ulmer were also on target for the Austrian champions as they moved top of Group E.
The match also marked the first time that an American manager took charge of a Champions League match, with former New York Red Bulls boss Jesse Marsch leading the Austrian side.
It’s a 6-2 final. Jesse Marsch is not just the first American to coach in the Champions League, but the first American coach to win. The supporters’ section chants U-S-A! U-S-A! as Marsch and the team approach. pic.twitter.com/qlnBgFeNVo— Paul Tenorio (@PaulTenorio) September 17, 2019
Norway international Haaland, who had already scored 11 times domestically heading into the match, took just two minutes to open his Champions League account when he fired low into the left corner from inside the box.
He soon doubled their advantage when a quickfire counter-attack ended with the teenager being sent clean through and he made no mistake, tucking confidently inside the right post.
A poor Genk clearance was then punished as Hwang steered a shot low inside the right post after being fed by Zlatko Junuzovic.
Genk gave themselves a glimmer of hope five minutes before the interval courtesy of a sliding finish from Colombia defender Jhon Lucumi after Salzburg had failed to deal with a set-piece.
However, two quickfire Salzburg goals - the first a close-range finish from Haaland to complete his hat-trick before Dominik Szoboszlai converted Takumi Minamino's cross - ensured the contest was over before the break.
Haaland became the first teenager to score more than once on his Champions League debut since Wayne Rooney's hat-trick for Manchester United against Fenerbahçe in September 2004.
Mbwana Samatta's header pulled one back for the visitors, yet Ulmer restored the four-goal advantage midway through the second half with a tidy finish after good work again from Junuzovic.
Samatta was initially shown a red card for a challenge on Junuzovic only for the decision to be overtuned by VAR.
What does it mean?
Despite this being a hugely impressive result for Salzburg, they still face an uphill struggle qualifying from a group also including European champions Liverpool and Napoli. This result shows they will be no pushovers, however, and could be capable of causing an upset, particularly at home.
Haaland heroics won't go unnoticed
Any hope Salzburg had of keeping their prized asset under wraps is certainly gone now. Haaland well and truly announced himself on the European stage with a devastating display in front of goal that is sure to have caught the eye of the continent's big guns.
Wooden spoon awaits Genk
Given the other sides in the group, bottom spot surely awaits Genk. The gulf in class between them and Salzburg means a tortuous campaign is likely to lie ahead for the Belgian side.
A trip to Anfield awaits Salzburg on Champions League matchday two on October 2. Things could get interesting if they earn a result on Merseyside. Genk, meanwhile, face a Napoli side buoyed by that win over Liverpool.
