But his response was immediate and very impressive, as he only needed 17 minutes to get himself back onto the score sheet.
It was also the 21-year-old’s 14th goal in just eleven appearances for Marco Rose’s title challenging Dortmund side.
While Dortmund have not given up hope of retaining Haaland, the Norwegian is expected to sign for one of Europe’s top clubs when his £63m release clause becomes active.
But United feel Rangnick’s impending arrival, as well as the fact he is scheduled to remain at Old Trafford on a consultancy basis for two years, could give them the upper hand over their rivals.
Haaland was moulded in a Rangnick inspired environment, as he rose to prominence at Salzburg during the German’s spell as sporting director at the club.
