Villa supporters have been voicing their opinions since the 3-0 defeat at Anfield left their side two points above the Barclays Premier League relegation zone.
They were unhappy Houllier, who managed the Reds between 1998 and 2004, touched the `This is Anfield' sign above the tunnel on his way on to the pitch.
At the end of the game, the Frenchman waved to the home fans and did not acknowledge the travelling Villa support. Then in his post-match press conference, Houllier said: "If I was going to lose 3-0 to anyone, it would be Liverpool as I like Liverpool."
Houllier issued a midweek statement trying to explain his actions but without actually apologising. But he adopted a difference stance at his press conference ahead of the home clash with West Brom.
He said: "If the fans think (what I did) was to hurt them, then I am sorry because this was not the case. It was just done in a humorous way and I am hurting as much they are. I was probably more hurt because it was Liverpool. If it adds to the fans' dissatisfaction, they have to know this was not the case at all (to upset them). This was done in a sort of a humorous way. I am sorry. That's it. That's enough."
