Mino Raiola and the striker’s father embarked on a tour of big European clubs last week to gauge interest in the Norwegian ahead of the transfer window.
They held talks with Barcelona and Real Madrid in Spain and are expected to do the same with Manchester City, Chelsea and Manchester United soon.
But Dortmund remain calm about the striker’s future and they remain confident of holding on to the player beyond the end of the transfer window.
According to German magazine Kicker, the Bundesliga giants are not expecting Haaland to agitate for a move out of the Westfalenstadion in the summer.
A €75m buy-out clause will come into effect in Haaland’s contract next year but this summer it could take big money to snare him away from Dortmund.
The Bundesliga giants are expected to hold out for at least €150m before agreeing to sell the Norwegian in the coming months.
With his high wage demands and Raiola’s agent fees, the deal is likely to touch astronomical figures in a transfer market where money is expected to be tight at most clubs in Europe.
Haaland wants to play Champions League football but Dortmund have slipped seven points behind the top four spots in the Bundesliga this season.
