The Swans take on Ferguson's Manchester United next weekend at the Liberty Stadium.
Rodgers has accepted that there is a gulf between the two clubs, but remains confident that his side will be competitive.
"This club and this city have been waiting years to host such a great team, a great club and a genius of a manger," he told The Daily Mail.
"It will be a brilliant occasion and for me there's real excitement.
"We're in the business of winning, irrespective of style. We understand that we're a million miles away from other people in terms of budget, the size of the club and our resources. But we're here to compete."
Swansea are currently tenth in the Premier League table.
