The 21-year-old Blaugrana attacker says he hopes to play a pivotal role in his first game against Real Madrid at Camp Nou on Saturday
The 21-year-old joined the Blaugrana from Santos in the summer, turning down los Blancos in the process, and is determined to help his new side down Carlo Ancelotti's men.
“El Clasico is the most important game for any player," he told the club's official website.
"It’s the match every player wants to play in, and is the game where each player wants to play his best football.
"This will be my first Clasico and I hope to have a great debut, preferably with a victory.
“I remember the Clasico, I believe it was in 2005, when Ronaldinho scored two goals. That's the Barca-Madrid match I remember most.”
The Brazilian says he has spoken to Madrid defender Marcelo - his international team-mate- ahead of the game and says their relationship will not be affected by the result.
“Marcelo and I have talked a little bit about the Clasico. We have a fantastic relationship, he’s a good friend, but I told him that Barcelona are going to win,” he added.
“I think the anxiety is the same before any match. I understand that we’re talking about a very important Clasico but I think that butterfly-in-the-stomach feeling is the same before any game."
