Good show against Spain will help silence the Brazilian's critics.
Confederations Cup: Brazil's Neymar has chance to silence critics in final against Spain
Neymar has already done a lot at the Confederations Cup to erase doubts about what he can do for Brazil.
Another good performance in the final Sunday night against Spain and few will be able to dismiss him as the future of Brazilian football.
Neymar made headlines across the world before the Confederations Cup by signing with Barcelona, but he arrived at the World Cup warm-up tournament marked by lacklustre performances in the famous yellow and blue outfit.
He quickly changed that by scoring three goals in four matches, leading Brazil to the much-anticipated final against Spain.
The 21-year-old striker was voted man of the match in the team's first three games and was decisive again in the semi-final against Uruguay.
"I'm really happy with how things have turned out for me and for the national team so far," Neymar said.
"We only have one match left and I hope we can play well to finish off with the title."
The decisive match against the world and European champions Spain at the Maracana provides the perfect stage for Neymar to lift his first significant title with Brazil and to try to prove his critics wrong for good.
He has been waiting for that chance for a long time, and had said before the tournament began that "it would be a dream come true to play" the final against the Spaniards.
"I'm anxious already," the former Santos striker said. "This is a match that can stay with me for the rest of my life. I will be defending my country, with the entire world watching."
Brazil coach Luiz Felipe Scolari said Neymar has already proved his worth regardless of how he plays in the final.
"Barcelona must be beaming seeing what he has been doing here," Scolari said.
"He has been playing well, making a difference against European defenders."
Wearing the No 10 jersey, Neymar opened the scoring for Brazil in the opening group match against Japan and also in the second against Mexico. He netted his third with a well-placed free kick against Italy, and he also assisted in both Brazil goals on Wednesday against Uruguay in their 2-1 semi-final success.
"Neymar is our idol, he is the people's idol," Scolari said. "He has had a nice string of matches and everybody is happy about that. It's important for him to be going through all of these different situations with Brazil because it's something that will make him even better in the future."
Neymar attracted everyone's attention with great performances with Santos in Brazil, but critics were quick to downplay his potential after he failed to replicate that same success with the national team.
He was often criticised for diving, an issue that came up again during the Confederations Cup when the Uruguay captain Diego Lugano publicly accused the Neymar of trying to "fool the referees and the rivals".
The remarks prompted the Brazilian football federation to put out a lengthy statement in the player's defence.
"It's worth repeating that Neymar doesn't need to resort to diving to play the type of football that is enchanting the world," the federation said.
At the tournament Neymar has appeared to go to ground easily on occasion, but has also looked more muscular and resistant to some of Europe's best and biggest defenders.
He had been struggling before announcing his move to Barcelona. He had not scored in nine matches and many doubted whether he would come through for Brazil.
The Confederations Cup is his third significant competition with the Selecao.
He helped Brazil's Under 20 squad win the South American championship in 2011, but his first test with the senior team was the 2011 Copa America, when Brazil was eliminated by Paraguay in the quarter-finals.
The second was at the London Olympics last year, when he was the star of the Brazil squad that was favoured to win its first Olympic gold medal in football but left with silver after a loss to Mexico at Wembley Stadium.
Neymar was among the players loudly jeered by home fans after playing poorly in a 2-2 draw in a friendly with Chile earlier this year.
That seems a long time ago.
"The Brazilian fans are completely behind us now," Neymar said.
"They are supporting us no matter what and hopefully they will be our 12th player again on Sunday to help us win this title."
