Barcelona signing Neymar is excited about the challenge facing him as he prepares to prove himself in Europe.
The 21-year-old ended his long stay at hometown club Santos by signing a five-year deal with the La Liga champions.
The highly rated attacker, who was chased by several European clubs, said it was difficult to leave Brazil but wants to enjoy his new test.
"It was tough (deciding to leave Brazil), but it was a decision I've made with my family. It is a dream turning to reality me," Neymar said.
"It's a kind of bittersweet though because I am very happy but sad of leaving the club that I love and the city where I grew up, where I played for nine years.
"At the same time I am facing a new challenge, it was my dream as well and now I want to enjoy every moment."
Neymar joins a star-studded Barcelona squad and will play with the likes of Lionel Messi, Andres Iniesta and Xavi next season.
While linking up with the stars makes him nervous, Neymar said he was focused on Brazil's Confederations Cup campaign in June.
"I have butterflies in my stomach because I will be playing with s great names such as Messi, Xavi, Iniesta, Daniel Alves and Adriano," he said.
"I am really looking forward to joining them but now I must be focused on the Confederations Cup, which is the most important thing, and get the title to Brazil."
As Brazil prepare to host both the Confederations Cup and 2014 World Cup, Neymar believes they can be successful at both tournaments.
"I really think that Brazil still plays some of the best football in the world. We are fighting for this," he said.
"We are full of talented players that can take us to the top."
