Mouctar Diakhaby - Lyon
The imposing French defender, who has also been scouted by Manchester City, is attracting plenty of interest from the Blues. Lyon, however, are expecting a fee in excess of £30m for their 20-year-old talent, which could prove to be a deterrent given that he has not been a regular starter this season.
Ross Barkley - Everton
Having failed to sign him on transfer deadline day this summer, Chelsea will return for Barkley in January. Given that the 23-year-old's contract expires at the end of the season, Everton are reportedly willing to cash in at a lower price than the £35m agreed in August.
Alex Sandro - Juventus
Conte is refusing to give up on the Brazilian defender, who would provide healthy competition to Marcos Alonso in the left wing-back role. Despite in dip in form and recent negotiations for a new contract at Juventus breaking down, Chelsea still face an uphill battle if they want to convince the Italian champions to sell mid-season.
Lucas Moura - Paris Saint-Germain
The Brazilian forward has fallen down the pecking order in France since the big-money arrivals of Neymar and Kylian Mbappe. PSG are also under pressure to recoup some of that cash and could sell the Chelsea target, who is yet to start a game this campaign, for as little as £27m.
Christian Benteke - Crystal Palace
With Michy Batshuayi still untrusted, Chelsea are in desperate need of a striker that can cover for Alvaro Morata. The Belgium centre forward, who is also attracting interest from China, could be the ideal man to do exactly that.
