Richarlison is planning to leave Everton this summer.
The Brazilian forward is ready to leave Goodison Park and has attracted interest from several clubs in the Premier League.
The Blues are yet to make their first signing of the summer even though Antonio Rudiger and Andreas Christensen have already departed the club.
Romelu Lukaku is expected to join Inter Milan on a season-long loan.
The Toffees demand a fee in excess of £50 million for Richarlison and Chelsea has targeted the Brazilian as a direct replacement to Lukaku.
He still has two years remaining on his Everton contract but it is expected that the 25-year-old will make a big summer move this window.
‘I’ve already made it clear to the board. I’ve already talked to Lampard too, with my agents and they know what I want. Let’s wait for June,’ Richarlison said last month.
‘Now I can’t talk, because when we talk about leaving a club I’m kind of like this, because of the history I have at Everton, the affection that the fans have for me. When we talk about leaving I’m a little speechless.’
