Villa have made a number of bids for Blackpool's prized asset Charlie Adam in the January transfer window, actions that have led Holloway to come out publicly on numerous occasions and make clear his displeasure at the their pursuit of the Scotland international.
But Houllier believes he has been unfairly victimised by his opposite number - pointing out Liverpool's interest in the Scottish midfielder has not led to similar personal attacks on their manager, Kenny Dalglish.
"I'm not happy with him. I'm not happy with what he said. But I'll keep that to myself. I think it's very, very unfair, that's all," Houllier said. "I just noticed this weekend that I was not treated the same way as our friend Kenny Dalglish, because funnily enough Ian said it must not come from Kenny when Kenny makes a bid, it comes from the club, and he treated me to all sort of things because the club - our club - officially did the right thing and moved to them, and he went back to the press having a go at me.
"So ... 'Easy target' as they say. Why is it just me?"
Holloway pinpointed director of football strategy Damien Comolli as the man likely to be responsible for Liverpool's bid, when quizzed about it last week.
