How much will one of the European giants have to pay to sign Erling Haaland when the transfer window opens on July 1? Borussia Dortmund want in the region of €180m for the prolific striker, according to ESPN sources. If Borussia Dortmund keep him another season, then they could lose him for €75m, with his reported release clause kicking in next year.
Prospective clubs -- like Bayern Munich, Manchester City, Real Madrid and Chelsea -- have to weigh up whether to pay the premium this summer, or wait a season and then be involved in one of the biggest transfer scrambles in recent memory.
