Watford attacker Richarlison is attracting interest from a raft of Premier League rivals ahead of the summer market.
Sky Sports says Manchester United, Chelsea and Everton are keeping tabs on Watford striker Richarlison.
The Brazilian forward had a terrific start to his first season in the Premier League, scoring five in his first 12 games.
Chelsea considered signing the Brazilian U20 international last summer, but the chance of regular first-team football under then-manager Marco Silva prompted the move to Vicarage Road.
Watford would only consider offers of around £40m for the striker they secured on a five-year deal for £11.2m.
