Neymar: Spain best team in the world
Neymar believes that Spain are favourites to win this year's Confederations Cup as hosts Brazil remain a side in transition.
June's tournament is seen as the only competitive test for Luis Felipe Scolari's squad to gel ahead of the 2014 World Cup, which is also being held on home soil.
The new Barcelona signing told Spanish TV station Cuatro that La Roja - who feature his new club team-mates, including Xavi Hernandez, Andres Iniesta, Cesc Fabregas and Gerard Pique - are ahead of his own country in terms of development at present.
"Spain plays the best football in the world at the moment," Neymar said. "Their players have spent years playing together, while in Brazil we are going through a process of change. We are getting used to each other and I hope we can play a great tournament."
The 21-year-old said he had agonised long and hard over the decision to leave Santos and join Barca.
"I have had days and months going crazy, but now it is over," Neymar said. "I am much more relaxed and happy. I chose Barcelona because I wanted to, it was a desire which came from my heart. I spoke with God and asked for wisdom and for him to show me the right path. Because of that I chose Barca."
Neymar added that he was looking forward to playing against Cristiano Ronaldo, who could have been a team-mate had he chosen to join Real Madrid instead of their La Liga rivals.
"Cristiano is an enormous player, and now it will be an honour to play against him," he said. "I hope I can beat him."
