Canaries' sporting director Stuart Webber brought Wagner to Huddersfield and the duo forged a formidable partnership that saw Huddersfield defy expectations to finish in the top six this past season.
"Small details made the difference". We must be focused and consistent.
"We fancy ourselves, definitely, and hopefully the crowd will really get behind us, intimidate Huddersfield and put them off their game". We have a final at Hillsborough, we will be ready.
To have come so close to a Premier League return last season is all the motivation Wednesday need this time around, according to right-back Jack Hunt.
They did so despite playing in a 15,000-capacity stadium and with a meagre budget and Kachunga sees similarities between their story and the one unfolding under David Wagner at the John Smith's Stadium.
A forgettable goalless draw offered little clue as to which Yorkshire club has the better chance of reaching the Wembley play-off final and claiming the estimated £170m prize that promotion to the Premier League carries.
The relentless march of football waits for no club. We will feel it from the stands on Sunday.
Huddersfield's Tommy Smith fired over before Wells had another chance when a loose ball fell to him eight yards from goal but Westwood was out quickly to deflect it wide.
Middlesbrough are also keen on Wagner as they seek a permanent replacement for Aitor Karanka ahead of next season's Championship campaign. "We were very good in the season and now we have to come to the quality of the semi-final".
Wednesday go into the match on the back of three victories from their last four home fixtures however The Owls have lost on home soil to Play-Off rivals Reading and Fulham this season.
Westwood then saved brilliantly from Wells to leave the tie perfectly poised going into Wednesday's second leg.
"However, the main thing was the clean sheet and we know with the players we've got that we can score goals".
Westwood was also forced into the second meaningful save of the game, after 71 minutes, when he deflected a Wells shot behind after another energetic attack down the Huddersfield left. When we played against them they didn't have too many opportunities so I think we can control them, especially at home when we play our game.
"We have enough Germans in our team and everybody knows Germans are able to win penalty shoot-outs!" "We don't have to manage the result or something, for me a good result against Wednesday is a win and nothing else".
