The home crowd will be right behind their team at the Cardiff City Stadium and as Andre Villas-Boas suggested to us, the Bluebirds can draw belief from a victory over Manchester City already this term.
Cardiff go into the encounter sitting mid-table while we travel to Wales with three wins out of four.
"It will be difficult," said Lewis, who impressed again in Thursday night's 3-0 win against Tromso, including an assist for our second goal.
"I’ve heard the Cardiff fans get right behind their team and it will be a challenge for us.
"You have to keep the crowd quiet. The first 10 minutes is important to try and keep the ball, try to quieten the crowd. Their fans will be up for it, so our target will be to try and get hold of possession and ideally, to score as early as possible."
