The Portuguese-born high-profile footballer manager is facing claims on two counts of tax fraud totalling €3.3m (£2.9m, $3.7m) dating back to 2011 and 2012 when he was in charge of Real Madrid according to media reports.
Earlier this month, Spain’s Prosecutor’s Office in Madrid filed a lawsuit against football legend Ronaldo for allegedly defrauding the country’s tax office of €14.7m (£12.9m, $16.4m).
Reports have since suggested that Ronaldo may have decided to leave Real Madrid amid claims he is angry at his treatment by Spanish authorities and that Portugal has launched its own tax fraud probe into the world’s highest paid athlete.
String of high profile cases
Spanish prosecutors have also indicted football player Predrag Mijatovic for tax fraud while allegedly working as an unlicensed football agent.
Ronaldo and Mijatovic’s indictments follow a string of other high-profile tax fraud cases in Spain such as Lionel Messi and Columbian Radamel Falcao, who have both fallen foul of Spain’s crackdown on tax evasion.
Mourinho managed Real Madrid from 2010 to 2013.
