Bucs play Comoros side Djabal FC in a Champions League first round clash in a month’s time, but have not yet finalised the venue.
The match will be played on the weekend of February 16-17.
"We are not sure where the game will be played yet and I am not sure what commitments the club has to other venues," De Sa told Sowetan.
"Obviously, we will have to respect any decisions that are taken on where the game will be played, but I am definitely in favour of keeping the game at 'home' in Orlando Stadium."
Last year Bucs took their Champions League clash against Angolan side Recreativo do Libolo to Nelson Mandela Bay Stadium, where they lost 3-1, and the club was criticised for taking the match away from Orlando.
