The Real Madrid forward is suspected of having pressured his former France team-mate to pay blackmailers who threatened to reveal an intimate video in which Valbuena featured.
On Tuesday, it was reported Benzema will go on trial from Wednesday, October 20 to Friday, October 22.
Benzema responded on his Instagram story, writing alongside a screenshot of the news: ‘Yes, finally. Let the masquerade end forever’
The striker’s alleged involvement has cost him his place in the France national team since 2015 despite his consistent high-level performances for the LaLiga giants.
Four other people will also stand trial in the case. Benzema denies any wrongdoing.
