Suddenly though, both Wednesday and Huddersfield find themselves within touching distance of the Premier League and all the riches and prestige that comes with it.
The Owls face a trip to the John Smith's Stadium on Sunday, before the tie will be decided at Hillsborough on Wednesday to see who progresses to the final.
This season's run-in could have been a lot more uncomfortable for Sheffield Wednesday as they spent the closing weeks with Fulham breathing down their necks. We worked so hard in the last couple of years to achieve this and we have to go all the way now.
"I think it's the biggest game in my career", Kachunga said of the second leg with the Owls.
We now play at home in front of our fans as a final.
"We are taking it step-by-step, the club needed an update which the chairman has done and we are now ready to go up".
"But we have to see it as a normal game".
Although they created little, boss Carlos Carvalhal will be pleased with how his side soaked up the pressure and kept their positional discipline throughout. "We did everything to play an open game".
"I didn't use Leicester as an inspiration where I say to my players, 'Look, they've done it".
"If we can get a goal or two, that just may be enough. We are massively better at home".
"It was to visualise to the players how far away it was - the last time they were in the Premier League".
Huddersfield had the better of the chances with Izzy Brown scraping the crossbar with a shot before halftime while Wednesday keeper Keiren Westwood made several vital saves.
Kachunga, who turned his loan move from Ingolstadt into a permanent arrangement in March, was a key figure in the Paderborn team that won promotion in the 2013-14 campaign.
"They had never played in the top division and Huddersfield have had a long wait", he said.
The two side's played out a dogged 0-0 draw in the first leg of their play-off semi-final on Sunday.
Although Wednesday are in the driving seat after chalking up their seventeenth clean sheet of the season, Wells does not believe that home advantage will count in their favour. "That you will be in the semi-finals of the play-offs, with a draw in the first leg, and there's a real chance for the final, I didn't have this in my head".
Here's what you need to know about Wednesday's vital match this evening.
