Neymar has admitted Brazil's 3-0 Confederations Cup final win over Spain came as a surprise to the 2014 World Cup hosts and has hailed their progress in recent months.
The Barcelona forward scored his team's second goal of the game shortly before half-time, sandwiched between a Fred double.
"I honestly didn’t expect this. I’ve just been speaking to my team-mates in the dressing room about how everything is coming together and how well things are going in every sense," Neymar told the official Fifa website.
"I’m really pleased that things have ended on such a high note, with our best performance to date. Winning this title is very important.
"It’s a massive step forward for the team and we are delighted to have achieved it. It was a great game between Brazil and Spain, one that the whole world stopped to watch, and we know that we played a fantastic match."
Brazil became the first team in history to win the competition three times in a row following their win over Spain.
