Manchester United, Chelsea Reportedly Interested in Watford's Richarlison

Manchester United, Chelsea and Everton are reportedly monitoring Watford winger Richarlison. 

According to Sky Sports, the trio have taken an interest in the Brazilian, but Watford have put a £40 million price tag on his head less than a year after signing him from Fluminense for £11.2 million.

The 20-year-old enjoyed an excellent start to the season, per OptaJoe:

However, he has not mustered a single goal or assist since that match with Crystal Palace on December 12.

The youngster has been involved in all 33 of the Hornets' Premier League matches and started all but three, so fatigue could be a factor given he has not had a rest since the start of the Brazilian season in April last year.

Watford are said to be concerned about the issue themselves, so if Richarlison stays at Vicarage Road this summer they'll be pleased for him to have a break, barring an unlikely call-up for Brazil's senior squad at the World Cup.

He's an exciting talent, so they'll no doubt be hoping their price tag will be enough to ward off the interested parties.

Richarlison's pace and technique make him a threat in the final third, but he's also robust, as ESPN FC's Michael Cox noted:

He boasts an impressive work rate, too. According to Squawka, he's won as many tackles as he has completed take-ons in the Premier League, 40, and he's also won a remarkable 109 headed duels and made 25 clearances.

The Brazilian has also drawn 86 fouls—more than any other player in England's top flight—though his passing evidently needs work, as he has completed just 64 per cent of his attempted passes.

Richarlison has a great deal of potential, but he needs to refine areas of his game and sustain his form throughout full campaigns before he's worthy of a place at clubs of United or Chelsea's calibre, let alone a £40 million transfer fee.

More time with Watford will give him the platform to do that, so he's likely better off staying put at this stage.
