Director of rugby Conor O'Shea was quick to announce he would keep faith with his young stars as Quins look to claim the season's first piece of senior silverware.
And Matthews is not surprised he and his fellow academy graduates are performing so well for the first team this year as the side chase an historic treble of trophies.
"We don't really talk about the treble to be honest but some people have been saying it's a quadruple because of the A League," said Matthews, who has started every game in the LV= Cup this season.
"It's almost like we feel unbeaten coming from that because it's a really similar team.
"We are a really tight knit group we've been playing together for a couple of years now and this is a good step up.
"It's almost like last week if we lost we wouldn't have had another game together this season."
The 21 year-old joined Harlequins' academy at the age of 15, making his Aviva Premiership debut on opening day last season, coming off the bench against London Irish.
This term he has impressed in the senior side, along with many other young hopefuls, and has ten first-team starts under his belt both domestically and in Europe.
And Matthews believes there is no pressure from the rest of the squad on the younger players ahead of the final.
"Because we all train together there's not much difference between the first team and the juniors," he added.
"If you asked the first team guys who is actually in the academy they wouldn't really be able to tell you.
"You see so many first team players that have come out of the academy, it's really positive.
"They rarely bring in a really big expensive old foreigner to play ahead of you and put you back down the pecking order.
"There's a clear pathway. If you work hard and play well there you'll eventually get there.
"They've put no pressure on us for the last game and for the final as well.
"The only pressure is the pressure we put on ourselves individually and as a team.
"Against Bath I felt like we were going out to just play and enjoy it and that will be the same again this week."
