Roman Abramovich is reportedly prepared to step up Chelsea's efforts to sign Borussia Dortmund forward Erling Braut Haaland.
Despite being available for a lower fee next summer, it has been frequently claimed that Chelsea are keen to sign the Norway international as soon as possible.
Dortmund are allegedly not open to doing business unless they receive an offer in excess of £150m for a player who has netted 57 goals from 59 appearances in all competitions.
However, Bild claims that Abramovich has given the green light for a bid of that size as he looks to tempt Dortmund into a sale.
The report suggests that Hakim Ziyech, Callum Hudson-Odoi and Tammy Abraham will be made available for transfer if Chelsea are successful with their pursuit of Haaland.
The trio were not regarded as first choice by head coach Thomas Tuchel as Chelsea won the Champions League and finished in the top four of the Premier League table.
