Neymar gave evidence on Tuesday in the court case into his signing for Barcelona in 2013 at a court in Catalan city.
He said he signed for Barça "because I wanted to play for them since I was a kid" and "it had always been my dream."
The Brazilian player confirmed that other clubs, including Real Madrid, showed interest but he "listened to my heart."
Neymar said: "I knew the rumours about other teams, but in 2013 I decided to go to Barcelona because it was my dream. There was the option to go to Madrid but I followed my heart. I always follow my heart and my heart said Barça. I had wanted to play for Barca since I was a kid because of the players they had."
On the negotiations between Santos and Barça, he said he was not involved in any of the conversations.
"I didn't take part in the negotiations," he said. "It was all down to my dad who always took care of these things. I sign what he tells me."
