Erling Haaland is among the most wanted players in Europe.
Real Madrid and Manchester City have shown the greatest interest in the services of Dortmund footballers.
But, "Sport" writes that the Norwegian wants to be transferred to Barcelona.
Dortmund's high demand could be a major obstacle for Barca, who have recently reportedly withdrawn from the race.
It is valued at around 150 million euros.
Haaland has scored 23 goals this season in 20 games that he has appeared for Dortmund.
