The defender's last action in British football saw him dismissed for fighting in Motherwell's June win.
The Tunisian left Scottish football in disgrace after two years with the Gers when he was involved in crazy scenes in the play-off final second leg with Motherwell at Fir Park in June.
Mohsni was pushed in the back by now-Leeds player Lee Erwin at the final whistle, before the 28-year-old punched and kicked the striker and was sent from the field.
It naturally led to condemnation from all corners of football, and the Scottish FA banned the former Southend United man for seven matches, despite his contract at Ibrox expiring in the summer.
Having been a difficult player to keep from trouble at Rangers before the flare-up at Fir Park, it was no surprise that those in charge at the club were eager to cut their losses on Mohsni.
In fact, the player's agent admitted to the Press Association, as quoted by the Guardian, that the defender would likely have to leave the UK such was the media focus on the incident and the backlash against the player's actions, while Sky Sports also stated that Mohsni felt former Rangers manager Stuart McCall failed to support him after the incident.
And so it has turned out as Mohsni has returned to France with Ligue 1 newcomers Angers, having played much of his football in the country earlier in his career.
Sky Sports reports that there is no word whether the French FA will carry the Scottish ban over for the player.
