FC Zürich
Chikhaoui was signed by FC Zürich on a five-year contract on 23 May 2007.
During the 2008 Africa Cup of Nations, it was reported that many clubs had scouts present to watch Chikhaoui play.[3][4][5] Unfortunately, after impressing at the African Cup of Nations he was forced to take time out to get a recurring knee problem treated. On 26 April 2009, he completed his recovery by returning to play for the Zurich first team. Weeks later he cemented his comeback with a goal and contributed, as a late substitute, to helping his team win and stay top in the title race.
He was part of the 2013–14 Swiss Cup-winning team and afterwards signed a new three-year contract until 2017. In the 2014–2015 season, he was appointed as the club's captain.
