The Frenchman, who made 37 appearances last campaign, is about to embark on his fourth season at The City Ground.
A tough-tackling, no–nonsense holding midfielder - he has won the affection of supporters due to his committed approach to the game.
He made a highly impressive start to his City Ground career and looked immediately at home with some driving performances, before a serious knee ligament injury in only his 11th appearance kept him out for five months.
Since then he has shown a lot of ability, attracting the interest of Premier League clubs along the way, and this season will be hoping to carry his potential into a string of convincing performances.
Moussi's earlier career was spent with French side SCO Angers, where he played 120 games in a six-year spell.
