Richarlison broke into his country’s national team in August after moving to Goodison Park from Watford for a reported £40million.
The 21-year-old has scored twice in his first four appearances for his country and is set to be involved against Uruguay at Arsenal’s Emirates Stadium on Friday.
Paris St Germain forward Neymar, who has hit 59 goals in 94 caps, is keen to aid his compatriot’s development.
“Everybody knows that Richarlison is a really great player and a really nice guy,” said Neymar.
“He has this trick to solve matches, to play well in great matches as he is doing now for Everton.
“I expect him to grow up, to keep developing in his career.
“I hope I can help him to achieve his goals and to help inside the pitch and even outside the pitch, as a friend, as a colleague.
“And if he is as smart as he is showing he is, he will try to keep with working well to be a really great player in the future.”
Richarlison celebrated his first Brazil goal – in September’s 5-0 win over El Salvador – by performing a pigeon dance with Neymar.
Neymar, who was accompanied by his young son at Thursday’s press conference, admitted he is under pressure to repeat the celebration against South American rivals Uruguay.
“My son already asked me and Richarlison to do the dance of the bird – the pigeon – in the next match,” he added.
