Brazil trio Alexandre Pato, Neymar and Ganso admit Argentina's Lionel Messi is the best in the world

The front men will look to strike fear into opposition defenders in this summer's tournament but think their biggest rivals have the world's best player
Brazil attackers Alexandre Pato, Ganso and Neymar may well come up against rivals Argentina in the latter stages of the 2011 Copa America, and believe they will face the world's best player in the form of Lionel Messi.

The trio have applauded the Barcelona forward ahead of entering the tournament, and despite their collective abilities, feel inferior to the Camp Nou superstar.

"Without doubt he [is on] another planet, because he does things others can not," Ganso told ESPN Brazil.

Milan forward Pato echoed his international team-mate's sentiments despite believing in his own and his side's qualities.

"I arrived in Milan when I was 18. But my time in Italian football helped me to mature. Today I am a complete player, the number 9 for Brazil. [However] when Messi plays [he] is the best.

"With Ganso, Neymar and Robinho [we] will have a great championship. I have [a] very good relationship with my peers both on and off the pitch. This tournament is very important to me," Pato said.

The comments come as Neymar admitted that he wanted to work hard at Santos to be as good as Lionel Messi, who he also believes cannot be outdone in world football.

The 19-year-old continued by stating his admiration for national coach Mano Menezes and hoping for a successful tournament.

"[He] is a great coach. I learn a lot from him. Hopefully this will be my Copa America," he concluded.

Brazil start their title defence against Venezuela on Sunday at the Estadio Ciudad de La Plata.
