Chelsea have plans for a £300m spend on three signings before next week’s transfer deadline.
The Blues have lodged a bid for Barcelona striker Pierre-Emerick Aubameyang.
Chelsea have made an offer of £15m plus Marcos Alonso for Aubameyang, while they remain intent on signing Wesley Fofana and Anthony Gordon, reports the London Evening Standard.
Aubameyang has been reluctant to leave Barcelona but Chelsea met his representatives last week in a bid to convince the former Arsenal striker to move to Stamford Bridge.
Chelsea have had two bids rejected for Fofana and will need to make the 21-year-old the most expensive defender in the world to sign him from Leicester City, who want more than £80m.
Everton winger Gordon remains keen on joining Chelsea. The Blues had a £45m bid for the England Under-21 international rejected last week. Everton do not want to lose Gordon but Frank Lampard has admitted he cannot offer assurances the 21-year-old will stay at Goodison Park.
