Everton striker Romelu Lukaku wants to complete a summer switch to Chelsea in time to make the pre-season tour of China, reports the Telegraph.

Lukaku has long been linked with a return to his former club after another impressive season at Goodison Park and it now appears that a move is edging closer.

The report suggests that Chelsea will have to pay somewhere in the region of £90 million for the player in order to complete a swift deal.

The Belgian striker is seen as the most likely candidate to replace Diego Costa this summer, who is being linked with a move away from Stamford Bridge.

A bid of £90 million would surpass the £89 million spent on Paul Pogba by Manchester United and make the Everton forward the most expensive player in world football.

Chelsea’s former striker has scored 24 league goals for the Toffees this season, four more than Costa has for the Blues under Antonio Conte.
