Barcelona president Joan Laporta has cast doubt on buying during the winter market.
Laporta admits financial fair play limits remain a problem for Barca.
He told Sport: “In the summer we set out with some plans and practically all the objectives were achieved.
“We have a more competitive and balanced team than last season. We are constantly thinking about how to improve it. Injuries have not allowed us to see the full potential of this team with all the new signings.
“To sign in winter we would have to incorporate players to improve what we have and it is not easy, especially taking into account that we still have fair play problems due to the elimination from the Champions League, which has reduced our budgeted income and LaLiga has already warned us that we will have to pay more for the team.”
