The 21-year-old, who is leaving Santos, juggled a ball briefly under a spotlight in a darkened warehouse by the port of Rio de Janeiro on Tuesday and then talked about his future after a long, fitful courtship with several European suitors.
Before Barca finally clinched a deal last weekend, other major European teams, had for the past two years sought to lure him away from the Brazilian club where he started his career.
"What I feel are chills in my stomach," the gazelle-like forward said referring to his impending move before adding that the nerves would not distract him from the Confederations Cup.
"Right now the focus is the Confederations Cup," said Neymar who will have to live up to a price tag estimated at about 74 million Brazilian Real ($35.82 million) by local media.
"That's what's most important - winning Brazil that title," added Brazil's World Cup hope, donning new orange boots being unveiled by Nike for reporters.
Despite Neymar's success at Santos, where his speed and skills have attracted global attention, he has yet to perform consistently at the same high level on the international stage.
