Chelsea have had a bid of €25million accepted for Internazionale midfielder Marcelo Brozovic, according to Squawka.
It is unclear if the Blues will pay the full amount or if they will offer midfielder Cesc Fabregas as part of the deal.
According to La Gazzetta dello Sport, Chelsea offered the Spaniard and cash to secure the services of the 23-year-old.
Juventus are also interested in the Croatian international who is yet to agree personal terms with the Blues.
If the transfer goes through, Brozovic will become Antonio Conte's fourth summer signing at Chelsea after striker Michy Batshuayi, midfielder N'Golo Kante and goalkeeper Eduardo.
And the Blues could announce two signings on deadline day having also reached an agreement with Fiorentina for the transfer of left back Marcos Alonso.
