Chelsea could launch a £35 million bid for Nice defender Youcef Atal if their two-window transfer ban is lifted in January, according to reports.
The Blues have made a mixed start to the season, with a win, two draws and a defeat from their opening four league games leaving them 11th in the Premier League table.
Chelsea boss Frank Lampard has been concerned by their frailties at the back, which as seen his side ship nine goals already and is planning to strengthen his rearguard.
Lampard is keen to make a move for Nice defender Youcef Atal, but may not be able to secure his services until next summer.
Chelsea are currently banned from buying players as a result of a two-window transfer ban for breaking rules regarding the signing of young players.
However, the club have contested the punishment and remain hopeful that the ban will be overturned, leaving them free to sign players in January.
Atal has emerged as a key player for Nice, who are managed by Arsenal legend Patrick Vieira, having joined the club from Algerian side Paradou AC in 2018.
He made 29 appearances for the club in 2018-19, while he's also represented Algeria 13 times at international level.
