The Owls will line up against Hull City for a place in the Premier League.
Carlos Carvalhal's men will take on the Tigers in the Championship play-off final after they knocked Brighton out in the semi-final.
And while their status as underdogs saw them go into their game against the Seagulls with little pressure, the fact that they have moved to within one game of the top flight means that the fans will be expecting a good performance and will be dreaming of glory, even if they still go into the game as outsiders.
And Pudil claimed that the squad remaining relaxed will be the key to delivering the victory.
"There will be 85,000 to 90,000 people at Wembley so there will be big pressure on both teams," he told the Star. "There's a lot riding on it on the financial side.
"But we have to try and be calm, go there and enjoy the game and we will see what happens."
With Hull's second leg against Derby County proving that they could be there for the taking if they are unable to get onto the front foot, Carvalhal will surely want to instruct his players to use their attacking flair to seize the initiative straight away.
That strategy saw Norwich take a 2-0 lead inside the first 15 minutes of last year's play-off final, and Carvalhal will be confident that if Wednesday adopt a similar approach, they are capable of killing the game off just as quickly.
