Everton are expected to tie up a £44m deal for the Hornets’ winger today.
Silva brought the 21-year-old Brazilian to the Premier League last summer in a £11.5m deal from Fluminense and was keen on being reunited with him once he made the switch to Goodison at the end of May.
Talks over a deal took shape in London on Thursday after Watford showed initial resistance to sell to the Goodison Park club following their pursuit of Watford’s former manager Marco Silva.
Richarlison, who attracted interest from Chelsea and Tottenham earlier last season, was left out of Watford’s friendly with Fortuna Dusseldorf on Saturday as he finalised terms with Everton.
Marco Silva played a pivotal role in tempting the Brazilian to Merseyside and is also hoping to convince Ademola Lookman to stay despite his desire to play first team football with Red Bull Leipzig.
Adam Partington recently spoke with former Wolves, QPR and Watford captain Gavin Mahon about the deal here.
