Antonio Conte has warned Diego Costa that “money is not everything”, after Chelsea’s Willian emerged as the latest target for the cash-rich Chinese Super League.

Chelsea are mounting a fierce stance against further bids from China for their star players and owner Roman Abramovich will refuse to sell unsettled striker Costa this season.

Costa was dropped for the trip to Leicester after a row with Conte and a fitness coach, while Chelsea fear his head has been turned by the promise of a mammoth salary worth £30 million a year from a club in China.

Oscar has already departed Stamford Bridge this month, joining Shanghai SIPG for an eye-watering £52million where he earns £400,000 a week, and his former team-mate Willian is also understood to be on the radar.

But Chelsea are taking a stand against the wealth of the Chinese revolution and Costa has already been told by team-mates to apologise to his head coach.
