Watford forward Richarlison has reportedly emerged as a possible transfer target for Manchester United.
Last summer, Richarlison moved to Vicarage Road for a fee of £11.2m and the 20-year-old has already established himself as one of the key players at the Hornets.
The Brazilian has failed to reproduce his form from earlier in the campaign but according to Sky Sports News, that has not stopped a number of clubs holding an interest in the player's signature.
United, Chelsea and Everton are said to be monitoring Richarlison's situation at Watford, who may decide to cash in on the player should they receive any offers of over £40m.
Paris Saint-Germain and Monaco are also allegedly keen on the South American, who has contributed five goals and four assists from 33 outings in the Premier League.
Richarlison still has over four years remaining on his contract.
