The Brazilian believes Pep Guardiola's men are extraterrestrial and claims he is attracted by the English and Italian leagues as well as La Liga and wants to play in Europe
The 19-year-old Brazilian forward was highly complimentary of the Spanish champions, with whom he has been linked with.
Neymar recently penned a new deal at Santos to stop him from moving to Spain until at least 2014, but he will rekindle associations with them in December for the Club World Cup.
"Barca are from another world," Neymar is quoted as saying on Record.
"They are aliens. Without doubt they are the best team on the planet.
"If we play against them it would be a pleasure and a great honour.
"It would be a dream final, but we need to think about the first game before that, which will be tough."
Neymar has also been linked with Chelsea and Real Madrid, and he admits the future could well be in Europe.
"My dream is to play in Europe. I do not know when but I will go one day," he continued.
"I have always liked Spanish football, but there are also other leagues that attract me like Italy or England.
"Always I have watched European football and, above all, the Champions League. To play against teams from France, England, Germany, that would be great."
The striker also believes Lionel Messi will win the Ballon d'Or once again.
"I think that Messi will win it. What he has done at Barca has been incredible. Second? [Cristiano] Ronaldo. Me, third? No, no. I am one of 23 nominees," he concluded.
Neymar could be involved in Brazilian Serie A action when Santos take on Atletico GO on Thursday night.
