During the regular season, there was nothing to separate the Owls and Brighton.
Both encounters finished 0-0 but of course, there must be a winner of two legs which take place on Friday at Hillsborough and Monday at The Amex.
The Brighton boss, who led his side to a third-place finish and only a goal difference off two behind second, says he expects nothing less than a tough and tight affair over the semi finals.
“When you go into the play-offs, there aren’t any favourites,” he said.
“There are four teams that all have qualities, otherwise they wouldn’t be there in the first place.
“It’s a very tough call between all four teams; that shows with the two results we’ve had against Wednesday this season.
“They are a very good side, they have goals in them and they know how to win a football match.
“I know some of their players very well so I expect it to be a tight affair, as you would expect in all play-off games.
“We know their dangers and that we can’t treat them lightly.”
