After just months in a Dortmund shirt, the Norway international has done enough since his January move from RB Salzburg to convince Real president Florentino Perez.
Okdiario says the Real supremo views Haaland as a natural successor for Karim Benzema.
Florentino and his board members believe they have three points of advantage in any battle for the striker's signature.
Firstly, the likely recalling of Norway teammate Martin Odegaard from his loan with Real Sociedad will help Haaland settle in Madrid. Secondly, Haaland's friendship with Achraf Hakimi, on-loan at BVB from Real, will also be a factor. Like Odegaard, Hakimi could also return to parent club Real for next season.
And finally, there exists a strong relationship between the two clubs, which would smooth any negotiations over a Haaland transfer.
