Early last year, the Frenchman was convicted for his part in a lovers’ brawl and ordered to stay at least 500 metres away from his girlfriend for six months.
According to papers seen by AFP, the prosecutor said that the 21-year-old player had breached those conditions and recommended a jail sentence.
In February 2017, Hernandez and his girlfriend were sentenced to 31 days of community service and six months apart for “domestic violence” after a brawl in which they exchanged blows.
In June, the couple were arrested together at Madrid airport returning from a holiday.

In Spain, if the accused has no criminal record, sentences of less than two years are usually suspended.
