Chelsea are hopeful of finalising deals for Tiemoue Bakayoko and Romelu Lukaku soon.
Antonio Conte is looking to make six signings this summer and has identified Lukaku as a priority target, while he hopes to partner Bakayoko with N’Golo Kante in midfield next season
The Blues have already agreed terms with free agent Willy Caballero and the 35-year-old keeper’s arrival is expected to be confirmed on July 1.
Chelsea also need a centre-half, but an agreement for first choice target Virgil van Dijk is unlikely after Southampton made it clear the Dutchman is not for sale.
Conte is keen on Juventus centre half Leonardo Bonucci and has also asked for another attacking midfielder, with Riyad Mahrez’s situation at Leicester being monitored.
Conte initially wanted Dries Mertens, but the Belgium international signed a contract extension with Napoli in May.
Mahrez has submitted a transfer request at Leicester, explaining his “fierce ambition” was behind the decision.
