As the summer transfer window enters its final weeks, Chelsea co-owner Todd Boehly is engaged in negotiations for at least three moves.
After two offers for Leicester City defender Wesley Fofana were rejected, Boehly intends to submit a third one.
Following the departures of Romelu Lukaku and Timo Werner, the Blues have already listed Pierre-Emerick Aubameyang of Barcelona as a potential addition to strengthen their attack.
In the upcoming days, Chelsea is also anticipated to make a bid for Inter Milan prodigy Cesar Casadei.
On Thursday morning, Fabrizio Romano, a football transfer specialist, tweeted: "Chelsea are working on numerous different deals.
After two bids were rejected, negotiations are still ongoing with the intermediaries in the Wesley Fofana sale; Pierre Aubameyang has been considered as a potential replacement since last week, but has not yet made a proposal to Barça.
"A new offer for Inter's 2003-born prospect Cesare Casadei is anticipated soon.
