The Taysiders struggled to produce the goods in front of their own fans last season and that is one of the areas McNamara wants to focus on during his first full season at the helm.
United got off to a solid start in last Friday’s goalless draw with newly-promoted Partick at Firhill and they now turn their attention to the visit of Terry Butcher’s Caley Thistle in their first game on home soil of the new SPFL season.
McNamara said: “It’s always nice to do well at your home ground.
“It’s important too because that wasn’t really the case last season and it’s something we have to try and correct.
“Every team wants to win as many matches as possible at home because it breeds confidence for the campaign.
“We gave ourselves a decent start away to Thistle last Friday and now we want to follow that up with a win at Tannadice.”
United host free-scoring Inverness who began their campaign in impressive fashion by beating St Mirren 3-0 on the first day. McNamara admires Butcher for the job he has done in the Highlands but he is more concerned about what his own players do on the day.
He said: “Inverness are always dangerous. Terry has them playing attacking football and they are a threat.
“But we have players as well who we feel can cause opposition teams problems.
“We can take plenty positives from our game with Thistle. The new players have settled in well and we feel we have a good balance.
“We know we have to take the chances which come our way as that can be the difference.
“As I always say to the players, it’s about what we do on the day. That won’t change and I’ve got confidence in this group of players.”
