Barcelona chief Deco expects a quiet January market.
However, Deco has hinted they expect Athletico Paranaense striker Vitor Roque will arrive in the New Year.
He told Mundo Deportivo: "We will be attentive to the market in January, but I don't think we will be able to make signings."
Deco was referring to the club's continued issues with Financial Fair Play.
On Roque, who was signed earlier this year before being loaned back to Athletico, Deco also said: "At the moment we have only talked about Vitor Roque with Xavi."
