For the fact that a club is declared financially unstable doesn't mean that the club doesn't have funds to run the club but instead it means that the club cannot afford further expenses outside the ones they are already running within the club so if Barcelona can afford an important player like Robert Lewandowski and can still pay his salary and other entitlement doesn't mean that the club has enough finance and if the media is wrong about the financial state of Barcelona then why didn't the club rise up and debunked it instead of keeping quiet and if you check Barcelona during the time of Lionel Messi you will know that the club wasn't as silent as they are now even though the influence of the Argentine international professional footballer also aided the team but yet Barcelona were financially capable so nothing is hidden under the sun, if Barcelona had enough cash i think they would have made some good signings so the financial status of Barcelona still maintains that the club is lacking funds.
This is important point but here we need to have few updates about this club Barcelona which is having reputation as one of the best in the world but recently due to have internal problems they are having troubling time like they are not able to bring new blood into team with they can now sell their few good players which are having high prices, so this will allow them to have better things for the future which will allow their team to have improved performance and quality which is needed for competing in La Liga top spot.
Real Madrid is doing impressive job, and now we are having few teams like Girona and Athletic Bilbao which are doing good work and having chance of staying at the top ranks which is surely challenging next few weeks are going to be important for them with Xavi is already gone and know how things will be work it's important for the clubs future.
