Despite being available for a small fee next summer, it has been repeatedly demanded that Chelsea be willing to sign the Norwegian striker Erling Haaland as soon as possible.
BVB is reportedly not allowed to do business unless he receives a promise of more than £ 150m for a player who has scored 57 goals in 59 games in all competitions.
According to the Bild claims that Abramovich provided a green light for the bid of that size as he looked to tempt Dortmund into a sale.
The report also suggests that Hakim Ziyech, Callum Hudson-Odoi, and Tammy Abraham will be offered a transfer if Chelsea succeeds in following Haaland.
The three could be considered as the first choice by head coach Thomas Tuchel as Chelsea won the UEFA Champions League and finished in the top 4 in the Premier League table.
