Sky Sports reporter Dharmesh Sheth has confirmed that Chelsea are very close to bringing Tiemoue Bakayoko to Stamford Bridge.
The 22-year-old has been heavily linked with the Blues and is expected to join the club in the coming days.
"They [Chelsea] have signed Caballero but nobody else. That could change soon," Sheth told Sky Sports News HQ.
"Talks continue with Monaco over the signing of Tiemoue Bakayoko. Monaco head coach Jardin admits that he is powerless from preventing his big players from leaving the club."
Willy Caballero joined after being released by Manchester City at the end of last season.
Recent reports have claimed that manager Antonio Conte is not happy with how the club has moved so far in the transfer window.
But Chelsea are expected to announce the signing of at least three players before the end of next week.
