The French-Tunisian, who signed a two-year deal at the club this summer, has also admitted that Rangers "have to win the league".
"I hope we can win every game, although it will be difficult. The last game I saw, it was hard to play against the team because they just defend and they just come to have a clean sheet or a draw," he told PA.
"We have some good players. We must concentrate in every game and I think we can beat every team. We have to win the league and we have had some good results. Now, we just have to keep going."
Rangers have scored 18 goals in their four victories in the league thus far.
