The Owls will come up against Hull for a place in the Premier League.
Carlos Carvalhal's men will face Hull City in the game that will decide who will take the final place in next season's Premier League after knocking Brighton out in the semi-final.
And the Owls skipper explained that the club's next game will provide him with an opportunity to realise a dream.
"It will be a great honour and I am sure I will do it justice. This game will probably be the biggest of my career. Definitely up there."
Though Wednesday will probably go into the game as underdogs as the Tigers finished nine points clear in the Championship during the regular season, they have shown that Steve Bruce's men would be foolish to assume that their task will be simple.
Carvalhal's side are the only team of the four that qualified for the play-offs that is yet to lose one of the two legs, despite having to get past the club that only missed out on automatic-promotion on the final day of the campaign in the semi-final.
And having drawn on both of the occasions that they have faced Hull this season, Loovens will have no problem convincing his teammates that they have more than enough quality to secure promotion.
