Guus Hiddink is urging Chelsea to keep hold of Brazil midfielder Willian despite a big money offer from China.
The 27-year-old has been a beacon of consistency in a season of struggle for the Blues.
And Chinese Super League side Guangzhou Evergrande have made a huge bid - worth £50million - for the former Shakhtar Donetsk player.
But Hiddink has warned the club against selling their prized asset.
He said: “Well I know Willian for many years, first of all as a person he is very down to earth and a very nice person - but that is not interesting.
“On top of that, he is doing a very good job in a difficult year. With his natural ability, he is still working very hard and sacrificing himself.
“He has the attitude to do so.”

Willian has been in fine form this season, becoming Hiddink's main go-to man as the Blues recovered from a horror start under Jose Mourinho which saw them lingering just a point above the relegation zone.
He has scored 11 goals in all competitions for Chelsea this season , with six assists to help atone for Eden Hazard's woeful form.
But he could be tempted by the move to China - where former Blues midfielder, and compatriot, Ramires arrived in the winter transfer window.
High profile players such as Jackson Martinez and Paulinho departed for China's top flight in what became a prolific splurge.
But the Blues may feel comforted by the fact that Willian still has two years left on his five year deal which was signed on arrival in 2013.
