Rivaldo says Richarlison still has it all to prove at Everton.
While he's earned plenty of plaudits at Goodison Park, as well as a call-up to the Brazil team for their friendlies against USA and El Salvador, Rivaldo wants to see more.
Rivaldo told the Daily Star: “Richarlison is producing solid performances in the Premier League and is clearly a good player, with great potential that could be really important for Brazil soon.
“Everton spent a good amount of money on his signing. Nowadays is hard to know if a player really deserves the money spent on him, because the transfer values are really high.
“But I believe he will justify the investment at Everton. He is making things happen.
“He was sent off after losing his temper and needs to understand that to become a top player he must relax and avoid this kind of behaviour.
“I'm sure he will learn from this lesson, after all it was his mistake and he is the one that will suffer with that and he certainly won't repeat it again soon."
