Financially, YES. If it's about the competition to get la liga trophy and it's not yet. Xavi has used his special skill to push barcelona exceeds their limitations. In result, barcelona's performance was always so amazing lately. Anything can change in matter of weeks.
Things will be worsening for barcelona next season. Club has no money to buy the new player.

When it comes to finances Barcelona have really had tough days but they would leave these days behind sooner or later. Their main problem has been with the league FFP rules recently.
Barcelona aren't having a very successful season which is a truth. The point losses they made earlier caused them to fall from the title race very quickly. Now the gap is eight points while we are in last nine weeks of the season. Real Madrid just need to make a terrible mistake from now on to let Barcelona jump in the race again. I don't expect that to happen. I'm just curious about who they will bring in Xavi's place after his announcement to leave.
