The Germans will demand at least £130m for the player who has also been drawing interest from Real Madrid.
A scoring machine, Haaland has shown he has what it takes to succeed at the highest level. He scored 28 goals and seven assists in 22 appearances for RB Salzburg before moving to Dortmund last January.
He has continued to put up prolific numbers at the Signal Iduna Park, having plundered in 12 goals and two assists in just 11 appearances.
With him continuing to impress, there has been speculation that he would be on the move once again this summer. United was keen on bringing in the player last January but missed out as the striker felt he will get more minutes at Dortmund.
Just 19, the Norwegian wonderkid is a serial scorer who cannot stop finding the back of the net. Dortmund are keen to keep hold of their prized possession and have placed a huge asking fee to ward off interest from other teams.
The player, to his credit, is focussed on performing on the pitch than respond to speculation off it.

Haaland is not the only Dortmund player who United are keen on. Jadon Sancho has continued to be linked to a switch to Old Trafford.
As long as the Norwegian keeps scoring, there will be no shortage of glances from Old Trafford. The very embodiment of an infallible scorer, it remains to be seen what the future holds.
