Chelsea will pay a fee of around €40 million (£35.3 million) to Lille, with Hazard having demanded wages of £4.6 million a year net of tax, so around £9 million a year for his new employer. That averages out at £170,000 a week.
In addition his agent, John Bico, who has conducted an aggressive auction has made it clear that he wants a fee of £6 million.
If all the demands are met and with Hazard expected to agree a five-year deal, it means the overall cost of the signing, fees and contract will amount to around £78 million which, even by Chelsea standards, is a substantial investment.
