Former Barcelona star Ronaldinho Gaucho is ‘always smiling’, according to the head of a Paraguayan jail where he is currently being detained.

As reported by Marca, the former football superstar was arrested last Thursday in the country when he and his brother attempted to enter using falsified Paraguayan passports.

The fake passport shows the former star’s correct name, birthplace, and birthdate, but it falsely prints that he is a naturalised citizen of Paraguay, report Football Espana.

A court decision on Saturday then kept the two Brazilians in preventive detention while an investigation into the incident was ongoing ahead of a trial.

“He is doing very well,” head of the jail, Blas Vera explained, as cited by El Mundo. “He is in a good mood, as you see on television. He is always smiling.”

His trip to the South American nation was to promote the charity “La Fundación Angelical,” which provides medical assistance to low-income children, while he was was also going to present his book Genio de la vida (Genius of life).
