Speaking on the Sports Agents podcast, the Basque boss said there will be changes this summer, with both outgoing and incoming transfers.
He said: “Probably some players will leave.
“We will try to keep as many as we can, especially the ones that have performed so well. But the club has to be ready for these movements.”
Iraola continued: “It's something that the club is used to doing.
“It is always difficult, because you are replacing players that have performed really, really well with question marks.
“We have also to sign new players, players who come with the right mentality, with the hunger to compete and to grow in their careers.”

“80, 90 per cent of the players will be the same,” he said.
“Probably one, two, three, I don’t know how many important players, can leave.
“We have to strengthen the team. Because even we always say, if we are the same team, we will be worse next season.
“Because that's the way this works. Everything is improving, improving, improving, and even if you keep the same players, probably it's not going to be enough.”
With Huijsen poised to make the move to Spanish giants Madrid, Iraola said he tries to help players if they need it with advice over moves.
“I will try to assist them,” he said.
“I will try to give them my opinion. There is a part that also you are happy.
“If these moves happen, you appreciate also how we've been able to help these players in this process and help them make such a big move.”

But throughout the campaign, Iraola has been clear – he has a contract at Bournemouth and he is very happy at the club.
He said: “But managers, we depend on results. I know that I have to win games. When we win collectively, everyone looks much better: the manager, the player, the owner. And when we lose games, we are not good enough for this club.”
Looking ahead, Iraola admitted he has been eyeing an early retirement.
“I think it's something that I've always had in my mind,” he said.
“I still have, I think, my seasons, and I am enjoying it. But I think this job carries also bigger responsibilities.
“I’ve been, the last 10, 12 years of my life, travelling with my wife, now with the kids, and they have to be always behind me, changing schools, changing houses. And I think there's going to be a moment, probably, where I have to decide to be like not the protagonist.”
