“I think we arrive in a great place. I am very relaxed and focused that we can get a result that builds on the first result.”
Celtic fired six goals without reply away to St Johnstone on Saturday, but it was to a pre-season when Rodgers lined up matches against some top opponents where he looked as ideal preparation.
“I track it back to pre-season,” he said. “The games that we played there, played some big teams and how we wanted to play at this level.
“We got off to a very good start in the last round, so we come here to a stadium very much like Celtic Park in that they breath football and we’re very excited by the challenge.
“We are under no illusions that we are up against a team who are challenging at the very top of elite football, but for us I’ve always said, whether domestically or away in this competition, it is about making us very difficult to play against with and without the ball.
“Offensively, Dortmund are very good. They lost some players in the summer, but I look at the team and they have some fantastic players in that middle to top area so will put you on the back foot at times.
“It is a top side with top players and we have to be right on it to get a good performance and result.”
Dortmund head coach Nuri Sahin is not underestimating Celtic’s challenge.
“I don’t think it’s fair to call them underdogs to be honest,” he said.
“You’re talking about a team who haven’t lost for many games and haven’t even lost a goal in their league. They were very dominant in their first match in the Champions League.
“They are a very prestigious club with amazing talent in their squad and a fantastic coach. It will be a challenge for us, but at the same time a big challenge, a huge challenge, which they didn’t have this season, playing in our stadium.
