Houllier wants Villa players to forget Tottenham reputation
But he stressed the importance of his own team not being overawed by the opposition.
Houllier said: "I saw them against FC Twente and they were impressive at times.
"It is a good attacking side and they really seem to enjoy their football. They finished fourth in the Premier League last season and have started well in the Champions League group.
"They are full of confidence but we will travel to them and give it our best shot. Sometimes the press talk more about the opposition. I came across that a couple of times (at Liverpool).
"Because of the name and prestige of the opposition, Milan or Barcelona, the press would talk more about them and forget about us. It was building up in the minds of the players that we were playing a monster or something very big.
"But if we are at that stage of the competition it is also because we have qualities and you have still got a chance, whatever the name of the opposition."
Houllier added: "I wanted to see Tottenham because they are a very good side but, when you see them, you see their strengths and weaknesses and football is about that.
"It is not just about seeing what problems teams can pose to you - but what you can pose to them."
