The Jags are the only team in Scotland with a 100% win rate on league duty this season, with wins over Falkirk, Dunfermline, Dumbarton and Hamilton Accies taking them three points clear at the top of the Irn-Bru First Division.
Next up is a trip to Livingston this weekend as McNamara, who picked up the Manager of the Month award for August, goes head-to-head with his former Bairns boss Hughes and the Firhill gaffer is expecting a stern test in East Lothian.
He said: "We want to keep our league run going but we know it will be a hard game for us through at Livingston. They will fancy themselves as title contenders and they have got some good players there.
"They had the upper hand on us last year over the four games so hopefully we can change that on Saturday and go there and keep the momentum going. They have got some good young boys there and Yogi has them playing good football as well.
"I worked with him at Falkirk and I know the style he likes his teams to play. I think it should be a good game of football but hopefully it is us that come out on top."
Thistle have been in superb as they have shot to the top of the First Division, with a num-ber of McNamara's players turning in a series of impressive performances in the opening weeks of the campaign.
Midfielder Paul Paton was last week named the McCrea Financial Services Player of the Month for August by Jags fans and McNamara admits he has been delighted with the 25-year-old.
He said: "Paul has been terrific for us so far. People might have raised their eyebrows when we moved him from right-back into midfield, but I always knew he could adapt and play that role well.
"He has got a real desire and a winning mentality. He is a fantastic player. He is very adaptable as well, he can play at centre-half or in a three or at right-back no problem at all. I think he is in his best position just now and he has been fantastic for us."
While those in possession of the first-team jerseys have thrived in recent weeks, the players on the edges of McNamara's squad have had to wait patiently for their chances to impress.
The Jags boss was able to ring the changes during last weekend's 3-0 Ramsdens Cup win over Raith Rovers and admits he has another selection dilemma ahead of tomorrow's Livi clash.
He said: "It was good to be able to get Aaron, Conrad and Christie on. It is about keeping everybody happy and giving everybody game time. James Craigen was on the bench on Sunday and was unfortunate not to get on and when you look at the players that weren't there, we have got a lot of competition for places.
"Kris Doolan was injured, Mark McGuigan is out, David Rowson is out and Ross Forbes has still to come in as well. There are a few selection problems ahead but they are good problems for me to have. As long as the team keeps winning, that is the most important thing."
