Chelsea boss Thomas Tuchel has pushed Borussia Dortmund and Erling Haaland with a deadline to get a deal done.
Football.London says Chelsea were believed to be one of the frontrunners to sign the 20-year-old with reports claiming the club had already agreed personal terms with the striker.
But Tuchel is eager to get the deal over the line sooner rather than later ahead of the new season.
Tuchel has set a deadline to help put pressure on Dortmund to cash in.
The Bundesliga club are desperate to hold on to their talisman for one more year, especially after letting Jadon Sancho join Manchester United.
It is understood Dortmund have set a £150m price tag on the forward, but the Blues see an offer of £135m more preferable.
