Fiorentina may learn on Friday whether they will be successful in their bid to sign Chelsea defender Branislav Ivanovic.
The player's agent, Vlado Borozan, has revealed that a five-year deal has been agreed in principle with the Viola but that they are now awaiting the say-so from Chelsea.
Borozan remains hopeful a deal can be reached with The Blues, despite the previous pessimism of Fiorentina's sporting director Pantaleo Corvino.
"The deal is at a decisive phase and by tomorrow [Friday] we will know how it will finish," Borozan told Sky Italia.
"My partner [Marko Naletilic] will be in London tomorrow to talk further with Chelsea.
"We have already reached an agreement in principle with Fiorentina for a five-year contract."
Ivanovic has made only intermittent appearances for the Chelsea first team since joining The Blues for £9 million from Lokomotiv Moscow in last January's transfer window.
