The Cherries go to the famous stadium tonight to meet Manchester United having won their past two games at the ground.
"I love to play at Old Trafford, to coach in this case at what I think is one of the best stadiums in the world,” he said.
“The problem is you face normally a top team when you play there and very good players. But I think the atmosphere there is really nice and I'm sure my players will appreciate it.
“But they will have to know that in those stadiums you have to be at a certain level that is very high and I hope we are.
“It’s true that we have good precedents but also I think we are playing this season against a team that is in a really good run.”
Indeed, Iraola believes United have made significant improvements this season.
He also said: “Especially the signings they've made up front. I think they've signed players, (Brian) Mbeumo, (Matheus) Cunha, (Benjamin) Sesko, players like Amad, now they are even more important.
“I think they have bigger threats. And we have to be ready to defend difficult duels like we did the other day against Chelsea for the full backs, for the centre backs.
“I think we will sometimes be really demanded because you have to defend very good players, sometimes in open spaces and we will have to be very good.”
