Spanish authorities opened a case against Mourinho in June, for alleged tax evasion during his time as Real Madrid boss.
The 54-year-old allegedly did not declare revenue related to his image rights in 2011 and 2012 and owes the Spanish state nearly £2.9million.
Mourinho’s agent issued a statement at the time denying the allegation and pointed out he paid nearly £23m in taxes during his stint in Spain, at an average tax rate of more than 41%
It also stated that he had reached a settlement agreement with the Spanish taxman in 2013.
Angel Di Maria, Javier Mascherano and Lionel Messi have all been convicted of tax evasion in recent years.
