Barca have first refusal on Gabriel as part of the Neymar deal.
"Someday I hope to become a Barca player. I've dreamed of this since I was little, from the moment I started playing football. The Spanish have already shown interest in signing me.
"I've always followed with admiration Neymar, my idol. He gave me a lot of help in my first few months here in Santos, before moving to Spain."
