Borussia Dortmund's new striker Erling Braut Håland came from the bench to score a brace as the hosts thrashed Köln 5-1 at the Signal Iduna Park on Friday.
Lucien Favre introduced the Norwegian teenage sensation in the 65th minute as he came on to replace Thorgan Hazard and scored in the 77th and 87th minute to make it five goals in two games to become the first player to do so in the division.
After an impressive 5-3 win away at Augsburg last weekend Favre decided to name an unchanged starting line up meaning hat-trick hero, Haaland again started on the bench.
Dortmund, however, started the match very well and took the lead in the first minute. Jadon Sancho dribbled into the box and picked out Raphael Guerreiro who made no mistake from 12 yards out to give Yellow and Black the lead.
Marco Reus doubled the lead just before the half-hour mark to make sure the hosts carried a 2-0 lead to the break.
Sancho made it 3-0 three minutes into the second half before Mark Uth could pull one back for Köln after finding himself in acres of space.
Dortmund gaffer, Favre then threw Haaland into the mix with 25 minutes left to play. The former Redbull Salzburg forward needed just twelve minutes to get on the score sheet as pounced on a loose ball after Guerreiro’s shot was parried by Horn, to restore Dortmund's lead.
Haaland then got on the end of Mahmoud Dahoud’s through ball beating the Köln goalkeeper before putting the ball in the back of the net from an acute angle to complete an emphatic 5-1 win.
Håland is yet to even play 90 minutes, in fact, he has just played 59 minutes and has 5 goals and is already Dortmund's third-highest top goalscorer in the Bundesliga this season and only Jadon Sancho and Marco Reus have scored more (11) but they have played 18 and 19 games respectively.
Dortmund now lies third in the Bundesliga, level on points with Bayern Munich but trail RB Leipzig by four points.
