Right Winger - Richarlison (Everton)

Much is expected from Brazil's Richarlison at Everton, given the fact he arrived on a £35.2 million transfer from Watford in 2018 and the skills he has shown in the Premier League.
The 2020-21 season was an underwhelming one for Richarlison, as Dominic Calvert-Lewin, the Everton attacker, dominated discussions. Richarlison made 33 league starts, scoring seven goals and providing three assists, and he will need to ensure he improves on his returns at Copa America 2021.
The 24-year-old is immensely gifted and is regarded highly by Brazil manager Tite. Richarlison has 25 caps and nine goals for Brazil, so a strong Copa America 2021 campaign could prove to be crucial for his team's title hopes at the tournament.
Centre Forward - Roberto Firmino (Liverpool)

It would be fair to say that Roberto Firmino's stock has declined in recent years after a few subpar individual seasons with Liverpool.
A flexible forward, Firmino has been a key component in Jurgen Klopp's Liverpool side over the years, but there have been signs that he has started to decline. The 29-year-old scored only nine league goals this season. While goals are only one part of his game, his ability to drop deep and link up play have also shown signs of deterioration.
Firmino has been a consistent starter for Liverpool under Klopp. At Copa America 2021, his ability to drop into midfield could be key, and his performances at the tournament could also have a say on his Liverpool future.
Left Winger - Neymar (Paris Saint-Germain)

Brazil and Paris Saint-Germain's superstar Neymar will be his country's key forward at Copa America 2021.
The 29-year-old has been his country's talisman for some time now, and at Copa America 2021, it will be no different. One of the best players in the game, Neymar already has 105 caps and 66 goals for Brazil. His creativity, goalscoring ability and world-class dribbling could all be on show at Copa America 2021.
Neymar and Paris Saint-Germain did not enjoy the best of seasons this time around. The Brazilian made only 15 league starts for the Parisien giants, scoring nine goals and providing five assists, so and more will be expected from the mercurial winger at Copa America 2021.
Other options: Gabriel Jesus (Manchester City), Vinicius Junior (Real Madrid), Everton Cebolinha (Benfica), Gabriel Barbosa (Flamengo).
