Barcelona are in a much weaker condition than Real Madrid financially now. This isn't everything for these teams to make it to the league title of course. Barcelona didn't have a better squad than Real Madrid last season but they still did a very impressive job thanks to Xavi. Now it seems like Barcelona aren't going to be able to add many new players to the team or to make many big signings. But it is still going to be up to them to close the gap with Real Madrid by performing much higher.
After disasters start and good end of last season now hopes are high for Barcelona as they are trying to have few players those are must for their better next season because right now they are having some serious financial problems which are preventing them for having their desired players but still management are aware about challenges which are going to be having them in next season.
Xavi's entry is also very good and timely, but now big challenge is waiting for him in next season as their arch rivals Real Madrid are also very strong and still adding few skilled players for having more improved performance even their few star players are still in good touch but still they need to prepare for all emergencies which can ruin any club season any time.
