BILD says Chelsea are right in the hunt and owner Abramovich has given his permission for a move worth more than €100million.
New Blues boss Tuchel could infuriate his old side by trying to lure their star striker away after one-and-a-half seasons.
He risks the ire of sporting director Michel Zorc, manager Hans-Joachim Watzke and any Dortmund fans who still hold him in high regard.
But Haaland is both one for the future and the here and now. Chelsea are desperately in need of a dependable presence up front and the Norwegian seems to tick every box.
