Guus Hiddink has urged Chelsea to keep hold of Willian amid reports of a Â£50million bid from the Chinese Super League.
Big spending Chinese side Guangzhou Evergrande have been tipped to launch a raid on Stamford Bridge for the Brazilian this summer, and they are believed to be prepared to double his wages to a staggering Â£240,000-a-week.
Interim manager Hiddink will leave Chelsea in the summer to be replaced by current Italy boss Antonio Conte but the Dutchman has urged owner Roma Abramovich to resist any offers for the 27-year-old regardless.
Willian has been one of the few bright sparks in a disappointing campaign for the Blues, and Hiddink has indicated the club should look to tie the forward down to a new deal rather than cash in, with his current contract set to expire in 2018.
He told Standard Sport: “I have known Willian for many years and as a person he is very down to earth and a nice guy.
“On top of that, he is doing a very good job. This year, in a difficult year (for Chelsea), he has been working very hard with his natural ability.
“When they defend and sacrifice themselves, he has the attitude to do so. ThatÂ’s why he is already, and can be in the future, a key player for this club.”
