The 20-year-old has had an impressive start to his debut season in England, so much so that Arsene Wenger and Antonio Conte are reportedly interested in luring him away from Vicarage Road.
The Brazilian joined from Fluminense for £11.2m in July and has scored five goals in 22 appearances for the Hornets, including a debut goal back in August.
Recently, the young forward has found it more difficult to score, his last goal was back in November, with rival teams starting to man-mark him.
Speaking to the English newspaper, Richarlison said: "Teams are already marking me individually, they are putting two players there on my side. Unfortunately it's difficult, but I'm doing what I can."
He continued: "I'm facing them, I'm making assists, I'm trying to score my goals. I'll keep working to keep bringing the results."
Watford drew 2-2 with Southampton on Saturday which proved to be controversial after Abdoulaye Doucoure used his hand to score a late equaliser.
