This is all over the spanish and catalan media. Cases tried a vote of no confidence in october, didn't get enough votes. Rosell responded that this is a reckless complaint, and he is not worried.
Legal action launched against Barcelona president Rosell over Neymar deal
Barcelona are defending president Sandro Rosell over claims from a board member of "misappropriation of funds".  
El Mundo Deportivo  reports that Jordi Cases is accusing Rosell of the "misappropriation" of €40 million during the transfer of Neymar. 
 
Cases proposed a motion of censure against Rosell at the beginning of  October, but there was not enough support. He then sent a 'burofax' (a  kind of registered legal document) to the Barcelona club in which he requested all the information about the transaction. 
 
"I believe that under no circumstances should the reasons for such a  huge transaction as this €40 million be kept secret. As a member and  thus a co-owner of our beloved club, I ought to have the right to know  for what reason €40 million euros have left the club", Cases says in the  document mentioned. 
 
He also thinks that Rosell "can't hide behind a confidentiality (clause)  requested by a third party so as not to give a suitable and consistent  answer about this additional €40 million payment". As he has not  received "a specific explanation", Cases has decided to start legal  proceedings. 
 A Barca spokesperson says the accusations are "unfounded and rash", as it "affects the club's image and credibility".
