Everton hope to sign Watford’s Brazilian forward Richarlison within 24 hours in a deal that could eventually be worth £50m.
The 21-year-old was having a medical with the Goodison Park club on Monday.
Toffees boss Marco Silva signed Richarlison for £11.5m from Fluminese in August 2017 when he was in charge at Vicarage Road, after the player had impressed in the Under-20 World Cup.
He scored five goals in his first 12 Premier League matches.
Richarlison has not netted since November, but Silva has been keen to bring him to Everton since he succeeded the sacked Sam Allardyce on 31 May.
Everton were believed to be willing to pay about £35m but there are likely to be clauses that will take the deal closer to Watford’s asking price of £50m.
The Merseyside club’s record signing is Gylfi Sigurdsson, who joined from Swansea in August 2017 for £45m.
