The [Cherries](http://www.bournemouthecho.co.uk/sport/cherries/clubnews/) head to the Tottenham Hotspur Stadium on Saturday, facing the home side under Frank for the first time.
Iraola said: “I think the approach is different. Thomas Frank's teams are always very well organised.
“Probably past season was difficult for them because of a lot of injuries, different circumstances. But I think it's going to be different now. The approach is different and I think they've started really well.
“Two games, two wins, they haven't even conceded a goal. So I know it's going to be difficult, but no, I don't expect so open games.
“I think it's going to be fast paced because they are quite physical. We are also physical.

Asked about preparation for the trip, and whether he could take anything from either Ange Postecoglou’s Spurs or Frank’s Brentford, Iraola explained: “95 per cent we look at the preseason games and games they played this season. 95 per cent.
“And then there is a part more related to individual matchups, individual things that we watch the last games we played against them.
“But no, most of them is how they prepare. But it's because also Brentford past season, there is nothing there.

Reflecting on his personal record against Frank – he has not beaten his opposite number – Iraola said: “Against Brentford, probably the worst game we played was the other day and it was not Thomas Frank in charge.
“I think even past seasons both games I finished quite happy how we played but we didn't win.
_(Image: Bradley Collyer/PA Wire)_ “But I think we were, especially away, I remember that game we played well but no, I think it's completely different also how they are playing comparing to Brentford they are now dictating the games much more.
“The first day especially at home against Burnley they were dominant and then they won 3-0, not easy. It’s never easy in the Premier League but it was a solid performance. I think the other references City, PSG could be tricky.
“They've done very well but they are different games. We are not City or PSG. The reference will be more the game they played against Burnley but they are very good. They were very good past season and I think they are going to be for sure better this season.”
