The Portuguese has been accused of tax avoidance in Spain and in the aftermath of those reports, it emerged that he wants a new challenge away from Spain having achieved all he can with the 12-time European Champions.
A host of football stars have run into trouble in Spain over suspected tax fraud related to image rights, with Madrid forward Cristiano Ronaldo summoned to appear in court on July 31 to answer four counts of tax evasion of 14.7 million euros.
According to Cadena Cope, the star of Real Madrid has chose to pay the staggering amount and reached an agreement with the judges.
Facebook/CristianoRonaldo has expressed his desire to transfer back to Manchester United.
All the cases involve income from image rights on endorsement side deals made by players, not salaries paid by clubs. Real Madrid and Man United are not directly involved.
"Jorge Mendes (Ronaldo's agent) told me that Cristiano was angry about how he had treated the media, but we must always look for a solution for everything". Atletico Madrid striker Radamel Falcao and Real Madrid defender Fabio Coentrao, who have also been accused of tax fraud in Spain, are also clients of Mendes.
Mourinho, who has won 25 trophies with clubs in Portugal, Italy, Spain and England, managed Real from 2010 and 2013, winning the Spanish league and the Super Cup in 2012 and the Copa del Rey in 2011.
'The Spanish government in turn, through the tax department, issued a certificate in which it attested that he had regularised his position and was in compliance with all his tax obligations'.
In addition, they say he only declared 11.5 million euros of Spanish-related income from 2011 to 2014, while what he really earned during that time was close to 43 million euros.
Ronaldo has denied any wrongdoing, while Real Madrid released a statement saying they had "full confidence" in their player and were "absolutely convinced that (he) will prove his total innocence".
The 54-year-old Mourinho, who coached Real Madrid from 2010 to 2013, was accused of "two offenses against the public treasury", the prosecutor's office said in a statement.
Prosecutors accuse the Portugal global of evading tax via a shell company based in the British Virgin Islands and another in Ireland, known for its low corporate tax rate. A Madrid judge will decide if the matter goes to court.
Last year, Lionel Messi was found guilty of tax fraud along with his father and, though the Barcelona star was sentenced to 21 months in prison, did not serve time as it was suspended.
