Bleiberg is concerned United will use negative tactics to kill off his team's game at Hindmarsh Stadium on Friday and told the Adelaide Advertiser his focus on entertaining and attacking set him apart from the average coach in the competition.

Vidmar took the criticism on the chin but thought Bleiberg's views may not be accepted by others.

"Everyone has their own opinions, that's fine, I'm certainly not offended and I have got a job to do here and the job is about trying to put out a team that is going to be competitive and to win," he said.

"If the comments mentioned a few days ago were true, it doesn't affect me one bit, but it's denigrating to the other coaches.

"Because if 'Mr Average' coach is not just me, it's every other coach in the A-League."

It's the second time in three weeks the Adelaide United coach, and his team, have come under fire for their defensive mindset.

Perth Glory coach Dave Mitchell likened the Reds' game to old-style English football before their season opener.

Vidmar said the comments could mean opposition teams were unsure how to breakdown the Reds' defence.

"They might be a little concerned about us," he said.

But Vidmar did agree with Bleiberg's comments about attacking football.

"If you have a look at that game Melbourne and Brisbane last week for the fans, it's brilliant, three goals, very open game, probably not great for a coach, probably both coaches would be pulling their hair out," Vidmar said.

"Everyone wants to play a nice attacking brand of football but you also need the players. They've certainly got those types of players who can do that.

"We are a little bit different so we'll play to our strengths and I'm very confident in our team and our group."

Gold Coast have entered the competition with style with a cashed-up squad and a private jet which flies them interstate for fixtures.

In contrast the Reds have been careful with their pennies after some tough financial times during the off-season.

But Vidmar said his club was not envious of the new franchise.

"The beauty of forming a new team in the A-League is that you can sit back and watch what the other clubs have done over the last three or four years," he said.

"And when you've got an clean slate, you can do what you like and you've got time to pick the right players. Of course you are you are going the pick the best players."
