Despite admitting to tiredness after his latest round of international duty with Brazil, the talismanic forward expects to play his first club game of the season on Saturday
The forward helped Brazil to World Cup qualifying wins over Ecuador and Colombia, netting once in both games.
Neymar landed back in Spain on Wednesday, just days out from Barca's encounter with Alaves at Camp Nou.
Despite fatigue, the 24-year-old says that he is confident of featuring for his club for the first time this season, having also led his nation to Olympic gold in Rio over the summer.
"Very glad to be home. Do I look like playing on Saturday? Sure," Neymar told reporters.
He added: "I'm a little tired now. I need to rest and then resume training with team-mates."
Without Neymar, Barca won their opening two league games of the season.
