Chelsea are considering whether to accept a £65million bid from Barcelona for midfielder Willian.
The Stamford Bridge club know of Manchester United's interest in the 29-year-old but would prefer to sell abroad rather than to a Premier League rival.
Marina Granovskia and owner Roman Abramovich are due to hold a meeting this week as they assess potential outgoings and signings for coach Maurizio Sarri.
The offer from Barcelona is the Spanish champions' third bid for Willian and though United have been expected to make a rival offer, the lure of Barcelona is strong for the Brazilian.
The funds will also help rebuild a squad Sarri can work with, especially as they continue to resist overtures from Real Madrid for Eden Hazard.
Chelsea remain in talks for Gonzalo Higuain from Juventus plus his teammates, Daniele Rugani, who Juve want to keep, and centre-back Mattia Caldara.
CSKA Moscow midfielder Aleksandr Golovin is also expected to choose Chelsea despite a rival £30m offer from Monaco.
Leicester City are understood to be among the clubs interested in Gary Cahill.
With Real Madrid continuing to push for Thibaut Courtois, Chelsea are considering Petr Cech, Joe Hart and Jack Butland for their goalkeeping options but a deal for Jordan Pickford will not be entertained by Everton.
