Richarlison's form for Everton during the 2018-19 campaign has reportedly attracted the attention of Barcelona.
The Brazil international moved to Everton from Watford during the summer transfer window, with the Toffees paying an initial £35m for the attacker, although the deal could eventually reach £50m.
The 21-year-old has scored seven Premier League goals for the Merseyside giants this season, while he has also registered three times in six appearances for Brazil since making his international debut in September.
According to the Daily Star, Barcelona have identified Richarlison as a possible long-term replacement for Luis Suarez, who will be 32 in the early stages of next year.
Richarlison signed a long-term deal with Everton upon his arrival during the summer, with the South American contracted to his Premier League club until June 2023.
