Chelsea have opened talks with Juventus over striker Gonzalo Higuain.
The Stamford Bridge side are yet to make a bid but the Italians value Higuain at £53million.
Both clubs are waiting for Higuain's brother and agent Nicolas to return from holiday in Argentina before progressing the deal.
Chelsea are looking to sell one striker, ideally before they sign Higuain, with Alvaro Morata, Michy Batshuayi and Olivier Giroud all targets for clubs in England and Europe.
Maurizio Sarri and Gonzalo Higuain worked together at Napoli for one season in 2015/16
According to reports in Italy, Roman Abramovich is in the country to help Chelsea push through a double deal for Higuain and Daniele Rugani.
Abramovich, who does not currently have a UK visa, is said to be helping agent Fali Ramadani in talks with the Serie A champions.
Corriere dello Sport claims Juventus chief executive Fabio Paratici met with Chelsea officials on Wednesday with the intention of agreeing a deal worth €100million (£89m) for both Higuain and centrasl defender Rugani.
Ramadani, who has a close relationship with Juventus, was hired by Chelsea to act as an intermediary between the two clubs and has succeeded in taking talks to the brink of an agreement.
Higuain has netted 55 goals in 105 games for Juventus since joining from Napoli in 2016
Cristiano Ronaldo's £105m move to Juventus means the club may come under pressure to move on some of its high earners in order to comply with UEFA's FFP rules.
Higuain's most prolific season as a professional came under Sarri at Napoli in 2015/2016, when he scored 38 goals in 42 appearances.
The Argentina striker moved to Juventus at the end of that season, and has made 105 appearances, netting 55 times.
Higuain also appeared at this summer's World Cup, but went goalless in all three group games before sitting out their second round defeat to France as an unused substitute.
Sarri has already brought in former Napoli midfielder Jorginho for £57m.
