Houllier will take charge of his first Villa match on Wednesday in the home Carling Cup third-round encounter with Blackburn.
The same competition brought Houllier his first trophy as manager of Liverpool in 2001 and he is hoping to end Villa's 14-year trophy drought to kickstart his reign.
"Winning a trophy would be fantastic for the club and a huge reward for the fans - it will come," he said. "Maybe what the club needs is more ambition and to show its fighting teeth.
"Sometimes when you are a good club, everything is fine and the comfort is there. Maybe what we need is to get out of this comfort zone and get results a bit more.
"The passion is there but the ambition to win things would do well at this club. The image is a nice club. We want to be a winning club, and a nice winning club."
