Chelsea have been told that they will need to spend at least £50m to sign Anthony Gordon from Everton, according to reports.
The Blues had a £40m offer for the forward rejected by the Toffees over the weekend.
Thomas Tuchel is keen to further bolster his attacking ranks before the transfer market closes for business on September 1.
Chelsea have already acquired Raheem Sterling from Manchester City (opens in new tab) this summer, but the departures of Romelu Lukaku and Timo Werner have left them short of options at the top of the pitch.
The west London outfit are also tracking Barcelona (opens in new tab) forward Pierre-Emerick Aubameyang, who could be sold just seven months after moving to the Camp Nou.
Gordon is being targeted in addition to the Gabon international, not as an alternative.
But Chelsea may have to make the Everton man their most expensive ever English signing, ahead of Sterling at £47.5m.
According to CBS Sports (opens in new tab), Everton value Gordon at £50m and will not entertain any offers below that amount.
If Everton do agree to sell Gordon, they may try to persuade Chelsea to include Armando Broja in the deal.
However, the Blues are reluctant to let the former Southampton (opens in new tab) loanee leave the club on a permanent basis.
They are open to sanctioning his departure on a temporary basis, but that might not be enough to satisfy Everton.
Chelsea would be open to including Michy Batshuayi as part of the package, with Frank Lampard keen to add another striker to his squad in the next few weeks.
Next up for Tuchel's side is a trip to Elland Road to face rivals Leeds (opens in new tab) on Sunday afternoon.
