Everton ace has had a strong start since move from Watford.
Everton paid around £40 million to sign Richarlison from Watford and the forward has had an excellent start.
Already this season he has scored six goals in 11 Premier League games.
He is going to pose a difficult threat for Liverpool to deal with heading into this weekend’s Merseyside derby.
Carragher said: “He (Silva)’s brought in Richarlison, who looks fantastic.
“He looks like one of the best signings in the league at this stage.”
Richarlison has scored more goals than any summer signing, ahead of Fulham’s Andre Schurrle on five.
Top scorers Sergio Aguero and Pierre-Emerick Aubameyang are just two ahead of Richarlison with eight goals each.
Richarlison’s reputation has increased further since his move to Everton, after he was called up to Brazil’s squad, and scored a winner for his country last week.
Netting against Liverpool this weekend will be another impressive check mark on his CV.
