Adriano has been probed for tax fraud by Spanish prosecutors, one of several Barcelona players.
He is alleged of defrauding tax authorities of €646,086 for failing to declare his image rights between 2011 and 2012 by prosecutor Ricardo Sanz-Gadea.
Adriano has paid the fee on March 7 and a judge must decide if the case is worth taking to court, a process which can be lengthy, just like in the cases of Javier Mascherano and Lionel Messi.
