But the Broadwood boss is realistic about the chances of that dream becoming a reality in the first round of the Challenge Cup on Saturday.
He said: "There's a huge rivalry there but we've got to remember that we're a third division team playing a full-time first division team. I loved beating Thistle as a player and, as a coach, I would love it.
"Hopefully we can go and put on a show and make the Clyde fans proud. I can promise that they'll see hard work and commitment from the players."
After hammering Colville Park Amateurs in their first pre-season game on July 10, the Bully Wee faced tougher opposition last Saturday in the form of Scottish Cup finalists Ross County.
The Staggies edged it 3-2 at Victoria Park however, Millar took many positives from the game.
He said: "I was delighted, we were playing a very good side. It was a bit of a team building exercise as well – doing the long trip up on the day and stopping off for a pre-match meal in Aviemore. I was pleased with the general fitness levels of the lads.
"The only disappointment was that we gave away two goals from set-plays, but we've not really worked on that yet. And, although we lost, the game was never about the result - pre-season games are about trying a few different things."
Clyde played an Everton XI in a friendly last night and will travel to Firhill on Saturday for their Challenge Cup tie with The Jags.
