Manchester United manager Jose Mourinho has been accused by a Spanish regional prosecutor of defrauding tax authorities of €3.3million, almost $3.7 million.
The complaint was made in court Tuesday and relates to the Portuguese coach's time in charge of Real Madrid.
According to the local prosecutor, Mourinho is under suspicion of having committed two offenses in relation to personal income tax.
Mourinho coached Real Madrid from 2010-13, guiding the club to wins in LaLiga, the Copa del Rey and the Supercopa de Espana.
He returned to Chelsea before arriving at Old Trafford for the 2016-17 season, collecting the Europa League and the EFL Cup during his first season with United.
The news follows reports in Spain that Madrid's Cristiano Ronaldo will appear in court on July 31 in relation to separate accusations of tax fraud.
United made no comment when contacted by Omnisport regarding Mourinho.
