Romelu Lukaku is flying to London to complete his £97.5m (€115m) transfer to Chelsea from Inter Milan.
The 28-year-old underwent the first part of his medical in Milan after the Italian champions agreed in principle a club-record deal to re-sign the striker.
The paperwork is now with club lawyers, and once that is formalised, Lukaku is expected to sign a five-year contract, worth £200,000 a week.
Inter have previously rejected two offers from Chelsea for the Belgium international, the second of which was worth £85m (€100m) plus left-back Marcos Alonso.
