The Scottish Premierships bottom two sides meet at Dens Park with the hosts a point behind St Mirren, who are six points adrift of 10th-placed Hamilton.
The Buddies beat Dundee in Paisley on the leagues opening day and both teams have changed their manager since then.
“No matter how, we must go and win this game. Its an absolutely massive game. Its a game where we need to win just to get back in touch.
“Its not always just about getting off the bottom. It gives you the opportunity to do that so it looks a little bit better but youre hoping that that gap to the teams just sitting above you is going to be a little bit tighter as well.”
Dundee boss Jim McIntyre and St Mirren counterpart Oran Kearney are both looking for a first win since being appointed and Dundee are yet to score under McIntyre.
Wins in recent weeks for Hamilton Academical and Motherwell have given the Lanarkshire rivals some breathing space over the bottom two, with Accies seven points off the bottom and Well eight.
“Over the course of the last month or so, weve come in after games after getting beat and results have been going our way,” Miller added.
“Us, St Mirren and Motherwell, were all playing each other over this 10-day spell and Motherwell have come out of that with two wins, something that we were looking to do.
“Thats put a little bit of a gap between us and Motherwell. Hamilton got a win as well. For weeks we were getting away with it. Now, its kind of getting away ahead of us.”
Dundee boss Jim McIntyre has urged his team to do their talking on the pitch – and one man who is never short of a word or two is set to return to the starting line-up.
The Dens men need to speak up according to their manager to get themselves off the bottom of the table, whether its a bit of sharp criticism or a word of encouragement.
And that sort of attitude has been missing during the Dundee bosss short time in charge at the club.
Initially he played through the pain but then missed six weeks before returning from the bench on Saturday at Motherwell.
He came on alongside another experienced midfield man in Martin Woods and their manager is delighted to be able to call on them both in this weekends crunch clash with St Mirren.
I think in the modern game, if you speak to any manager theyll moan about the lack of talkers especially with the younger ones coming through with iPads and earphones and the rest.
Talking is something thats so important – we are too quiet and need to get louder, no doubt about it.
Its the easiest thing to talk to each other and pass information – turn, man on, whatever – and we can really help ourselves out in that way.
I dont mind arguments on the pitch, players need to let their team-mates know that something isnt good enough – but say it once and then encourage.
If someone hasnt done their job then we cant let people away with that because we have one common goal, to get the three points.
Some of our young players could be louder, no doubt about it. Sometimes you get that with a mix of nationalities as well.
McGowan enjoyed four seasons at St Mirren which peaked with a Man-of-the-Match performance in their League Cup Final victory in 2013 under Danny Lennon.
Since joining Paul Hartleys Dundee four years ago, however, the ex-Celtic kid has become a more and more influential figure in the middle of the park at Dens.
The ability to hold on to the ball in tight situations and move the ball up the pitch has been sorely lacking since he dropped out of the team at the end of September.
Not to mention his personality and experience which, in a midfield that has featured young players like Glen Kamara, Lewis Spence and Jesse Curran, can avoid some of the naivety that has been displayed at times this campaign.
Last week was a prime example as Motherwell took advantage of Dundees inexperience with David Turnbull given space to wander into and fire a superb strike into the net for the games only goal.
Dens boss Jim said: It was a great strike to beat us but we can do so much better with the organisation.
There was far too big a gap – at that stage we had changed to three midfielders and not one of them was in the vicinity – and Turnbull had acres to turn and pull the trigger.
Its some strike but, from our point of view, there has to be one of the midfielders in there.
