The Cherries and title holders Liverpool kickoff the Premier League later on Friday night at Anfield.
Last season, Liverpool won home and away against Bournemouth and Iraola said: "We didn't get any points (last season).
"We’ve never got one point against Liverpool (in Iraola’s time at the club). I think it's the only club that we've never got a point against
"I think we do certain things that are uncomfortable for teams but for Liverpool, because even if you play very fast and very demanding games, and very rock and roll, they are ready for it. They are the best ones doing this.
"So, we have to change a little bit the approach if we want to hurry them because it's a difficult matchup for us."
However, Iraola also insisted: "We don't want to be just the guests in their party.
"Its the champions first game of the season, someone has to be there in front of this.
"But no, we want to be something else and put them into more pressure."
