Willian has agreed terms on a new two-year deal with Chelsea, according to a report.
The Brazilian forward, who is currently away on Copa America duty, has been repeatedly linked with a move to Barcelona over the past 12 months.
Barca are rumoured to have recently revived their interest in the 30-year-old after having numerous offers knocked back last summer.
Despite their policy of only offering one-year deals to players aged 30 and over, The Sun claims that Chelsea have relaxed the rules due to their transfer ban.
Having already tied down David Luiz to a new deal, compatriot Willian is expected to follow suit by formally putting pen to paper in the coming weeks.
Willian, currently due to become a free agent in a year's time, started 42 matches for Chelsea in all competitions last season.
