The Owls will face the team that finishes third in the Championship in the semi-final.
The Owls have secured sixth place in the Championship so will face whichever side finishes third in the table. But while their free-flowing, attacking football has been a key part of their success this season, the fact that they are yet to beat any of the teams above them in the table this term may have tempted the Portuguese to set his side up slightly differently for the additional games.
But Carvalhal has claimed that after booking their place in the top six with a dominant display against a Cardiff team that could have moved to within one point of Wednesday had they won last weekend, the Owls will continue to play their way.
"A draw would have been enough against Cardiff [for a play-off place] but we played to win," he told the Star.
"We gave a very clear sign to the team that we wanted to win. We played three strikers in attack and went for the three points. That has been our philosophy since the beginning and we won't change anything in the play-offs."
Though Wednesday have not won against any of the top five, they have secured several draws and have given clear indications that with a bit of luck, they have the ability to beat any side in the division.
And with the Owls coming up against whichever team agonisingly misses out on automatic promotion, they will fancy their chances of using their momentum to get onto the front foot and win the two-legged tie before the game at Wembley that always promises to throw up some surprises.
