Chelsea are reportedly prepared to spend at least €100m (£86.98m) on Borussia Dortmund forward Erling Braut Haaland this summer.
While the Blues are well stocked for options in the final third, the respective situations involving Timo Werner, Tammy Abraham and Olivier Giroud mean that alternatives must be considered for the future.
Dortmund are aware that clubs will come calling for Haaland, with the 20-year-old having already scored 28 goals in all competitions this season.
According to Bild, Chelsea are determined to take advantage of the financial situation around Europe by lodging a big-money bid for the Norway international.
At a time when other suitors may have to restrict their spending, Abramovich is allegedly willing to hand Thomas Tuchel a substantial warchest for new signings.
Haaland has a release clause in his Dortmund contract which cannot be activated until the end of the 2021-22 campaign.
