The Norway international is the most sought-after player in world football after continuing his impressive form for Red Bull Salzburg at Dortmund over the past 15 months.
According to Sport1, however, it is a shootout between two clubs for the 20-year-old's signature.
The report suggests that Haaland will choose between Madrid or City, assuming both clubs are able to match Dortmund's nine-figure valuation.
Haaland has 33 goals in 34 matches for BVB this season, including 10 goals in seven Champions League appearances to top the scoring charts. body check tags ::
