Goal-machine Erling Braut Haaland took just 23 minutes to bag a hat-trick on his Borussia Dortmund debut.
The Norwegian striker was Manchester United 's top January target but instead decided to join the Bundesliga giants from RB Salzburg.
Haaland has wasted no time in showing what he's all about, smashing in three goals in the 59th, 70th and 9th minutes after coming on as a substitute.
His strikes helped Dortmund seal a thrilling 5-3 comeback victory over Augsburg in their first action since the German winter break.
Julian Brandt and English starlet Jadon Sancho also notched for BVB as they moved within four points of the league summit.
Such was Haaland's impact, he notched with his first touch in a Dortmund shirt with his side trailing 3-1.
Sancho then bagged the equaliser before Haaland grabbed a second and third to cap a remarkable turnaround.
His exploits will be a stark reminder to Old Trafford boss Ole Gunnar Solskjaer as to what he could've won.
Solskjaer coached Haaland at Molde but, with agent Mino Raiola representing the player, was unable to lure him to the Premier League .
