Monaco have rejected a £38.5m (€45m) bid from Chelsea for Lamine Camara.
The Blues are lining up replacements for Enzo Fernandez and have also been discussing a £52m deal with Roma for Manu Kone.
Roma boss, Gian Piero Gasperini wants to keep him, however.
Sky Sports News reported last week that Camara is also one of their top midfield targets.
Also, Ethan Nwaneri is set to leave Arsenal and join Borussia Dortmund on a season-long loan.
Football transfer expert, Fabrizio Romano, wrote on X: “EXCLUSIVE: Borussia Dortmund reach verbal agreement to sign Ethan Nwaneri from Arsenal, here we go!
“Season long loan agreed from Arsenal as Nwaneri said yes to this possibility overnight.
“BVB sources confirm salary will be entirely covered by the German club.”
Arsenal have also agreed a deal to sell Fabio Vieira to Hamburg.
The transfer is expected to be worth around £7.7m for the midfielder.
