Despite being in financial crisis, Barcelona team managed to win the title last season. Because their squad was strong enough. But there are several weaknesses within their squad this season. Players are facing injuries. As a result, Barcelona's defense is now quite shaky. Together they depend on Lewandowski to score. If Lewa does not perform well, it will be difficult for Barcelona to win the match. The team is not getting the expected performance from Gundogan. Barcelona will need to prepare big funds in the winter transfer window if they want to stabilize the squad. If not, they will not be able to fight for the title this season.
Less fund I doubt Barcelona have decision for signing new player in winter transfer, actually Barcelona need recovery on many position but difficult with financial make them have finding players with free agent for signing.
