"We have to switch our focus to this match," Jele told his club's official website.
"We know how to play in the Champions League and although beating the Tunisians here will be tough, I think we as a group we are doing some good work at training to stop them from playing here.
"We want to beat them by a huge score here and consolidate the tie away. It is not an easy match to play considering the fact that we are playing hosts first. We have the pressure from the fans who will be out in numbers supporting us. We are ready like I said and let us hope all goes well for us."
The lanky 26-year-old added: "We know they will come here to attack. They know that scoring a goal here sets them in good standings for the return leg.
"We are working on defending well and force them to stay away from our half.
"Psychologically and otherwise we are doing our homework and my wish is that everything works well until our last training day."
