Everton head coach Frank Lampard has sent a message to Chelsea in their pursuit of 21-year-old Anthony Gordon.
The Blues are looking to bolster their frontline before the transfer window comes to a close this summer.
While they have added Raheem Sterling alongside five other signings, Chelsea are still on the search for a lead number nine.
With both Timo Werner and Romelu Lukaku departing Stamford Bridge, the west London side may be left scrambling for a signing in the closing weeks of the transfer window to fill the gap.

Everton's Gordon has emerged as a lead candidate in the past couple of weeks.
Chelsea in fact have seen an offer of £45 million rejected by the Toffees.
Talks are still ongoing over the potential transfer with it reported that negotiations will take place over the phone due to Todd Boehly being set to be away from England.
With the Blues keen to add to their attack, Everton boss Lampard has revealed it would be "naive" of him to guarantee that Gordon will stay.
This could hand Thomas Tuchel's side a boost in their pursuit of the England U21 international.
While they have twice been rejected, it is suggested that a bid of around £50 million would see a breakthrough in the negotiations.
The former Chelsea legend has stressed that he would like to keep the youngster but they may have to face letting him go.
A large bid could see them fold into a sale and then use that money to bolster their attacking options.
Lampard shared however: "He is an Everton player... he has got huge value to the team and to me.
"He's in the squad for tomorrow, any chats I have with him are private."
Gordon though is reportedly hopeful of completing a move to Stamford Bridge as the talks continue.
In the Blues' attempts to sign Gordon, they may offer up fringe players.
Everton have previously been linked with moves for Armando Broja, Conor Gallagher, Billy Gilmour, Ross Barkley and Michy Batshuayi this summer.
Should Chelsea offer some of these players, it would cut deadwood from their own squad and also reduce the cost of the deal.
Other options have been monitored by Tuchel's side as well.
Former Arsenal striker Pierre Emerick-Aubameyang has been tied with a move away from Barcelona and back to the Premier League.
As reported by Fabrizio Romano, Chelsea held a meeting with the Spanish outfit which was 'very positive'.
It will be interesting to see the route Chelsea travel down, they have made youth a priority this summer, and have already acquired Gabriel Slonina, Carney Chukwuemeka and most recently Cesare Casadei.
An acquisition of Aubameyang would provide much needed experience and reliability up front, so there may even be potential of the Blues capturing both signings.
