The Frenchman has reacted angrily to comments made by Souness in which the Scotsman made it clear that only former professional players could understand that Neill's X-rated challenge was simply part of the game.
Houllier, fully aware that the broadside was clearly aimed at him, has revealed that the growing feud between him and the former Anfield manager is far from over.
Houllier said: "Carra was injured at 3.10pm on Saturday and the apology came 48 hours later. It was absolutely pathetic.
"If anyone thinks I'm going to give up on this, they are wrong. Maybe I have not played at the highest level but I have managed at the top longer than Graeme Souness. I can tell you it's not often you get a game with two players suffering broken legs after 15 minutes.
"This comment about not playing at the top was obviously directed at me. I see Graeme Souness saying with his hand on his heart there was no intent. Look at the photographs. That was a tackle which was meant.
"If that's what you do when you go for the ball, I'm surprised. I understand Souness wants to defend his player but I don't understand his attitude.
"Maybe Neill is a good footballer but he behaves like a bad gentleman. I am not saying he is a coward but I thought the tackle itself was cowardly.
"Maybe Souness is a good manager but he should put aside his bad feelings for Liverpool.
"Of course I understand these things happen. But what is unacceptable is their lack of grace and dignity. I noticed the TV cameras went straight to Blackburn yesterday and not here and yet it is we who have the two players with broken legs.
"It must have just been a coincidence the cameras were at Blackburn's training ground.
"People have mentioned Steven Gerrard's tackle on Gary Naysmith last season, but you will remember Stevie apologised immediately before Gary had even been changed in the changing room after the game.
"To be directing criticism at me and blaming me for the upset is wrong. Carra has a broken leg and is distraught. The apology should have been immediate."
