The two sides meet on Saturday with Wasps on top of the Premiership and Saracens two points behind in third, with Exeter sandwiched between them.
The winner will guarantee themselves a home semi-final in the play-offs.
"When the fixtures came out, I looked at this one and thought 'this will have a prize on it'," said the 49-year-old.
"It has proved to be the case."
Wasps, who have headed the table throughout 2017, secured a second successive play-off semi-final despite losing at Harlequins last weekend.
But they are level on points with Exeter - and a Saracens victory at the Ricoh Arena could leave the club in third position.
"We targeted 75 points at the start of the season, which on average would have given us a top-two finish in previous seasons," said Young.
"We've exceeded that, but we still have Exeter and Saracens around us."
The Coventry-based side, who have won all 10 league matches at the Ricoh this season, are the only side in the competition with a 100% home record.
But Saracens have only lost one of their past 12 meetings with Wasps, and beat Young's side in the Champions Cup semi-final last season on their way to the title.
"It's a new experience," added former Wales international Young. "There's lots of talk about the weekend, and lots of people have already written us off.
"These players are not used to being in this position, and I'd be lying if I sat here and said there weren't going to be nerves.
"But this is what the hard work is all about. Through pre-season and right throughout this season, to arrive at this spot and make a big impression."

X Factor bosses confirmed that they're following doctor's advice.
The judge, who's been mentoring Italian singer Andrea Faustini, has been ill for several days.
Tulisa Contostavlos has been chosen to join the panel as a stand-in. It's thought she is a natural choice as she has been a judge on the show previously in 2011-12.
She also featured in the show this year as a guest mentor at Louis Walsh's judges house and during Jukebox week she chose Stereo Kicks' song.
The former Spice Girl didn't appear at an X Factor press conference on Thursday and missed rehearsals.
The 39-year-old joined fellow judges Simon Cowell, Louis Walsh and Cheryl Fernandez-Versini this series.
She was left with only one contestant in the series after Paul Akister was eliminated in the fifth week of the live shows.
Mel B appeared at the Royal Albert Hall in London on Tuesday where 20-year-old Faustini performed in a charity concert.
Last month, there were worries that Cheryl would miss an X Factor show because of a throat infection. However she eventually appeared as normal.
In 2011, then-judge Kelly Rowland missed a live show because of illness. Her last-minute replacement was a former winner of the show Alexandra Burke.
The bookies' favourite to win this year's competition is Fleur East.
The X Factor final is on ITV on both Saturday and Sunday nights.
