The 22-year-old winger signed a new deal in August to keep him at the club until 2018, but has since found regular opportunities in Gerardo Martino's side limited this season.
"I am content at Barcelona but we still have not advanced in the negotiation deal," he said regarding a potential move.
"It is normal that I desire more minutes in the team. I want to profit on my opportunities this season.
"I do not need to demonstrate anything on the pitch because the coach knows how I am at this club."
