Bournemouth have become accustomed to having major talent poached and, although Iraola insists he does not have another job lined up, he is expected to be in high demand this summer.
Before the season started, they lost three of their four first-choice defenders. Milos Kerkez joined Liverpool, Illia Zabarnyi moved to Paris St-Germain and Dean Huijsen signed for Real Madrid, for a combined total of almost £150m.
In January, attacker Antoine Semenyo joined Manchester City after his release clause was triggered.
However, the Cherries can reflect positively on each replacement proving successful. Adrien Truffert came in for Kerkez, Bafode Diakite replaced Huijsen and Rayan was signed as Semenyo’s successor.
The club hope Rose will follow the same pattern. He had long been regarded as a potential replacement for Iraola in the event of the Spaniard deciding to leave.
Bournemouth are impressed by Rose’s five years of experience leading clubs in the Champions League, as well as his Europa League pedigree.
He has played a role in the development of several leading players, including Erling Haaland and Jude Bellingham at Borussia Dortmund and Dominik Szoboszlai at RB Leipzig. Rose also enjoyed surprise success at Borussia Monchengladbach, qualifying for the Champions League with limited resources.
Those experiences would be key if Bournemouth are to qualify for Europe for the first time. Player trading continues to offset revenue limitations caused by the club’s relatively small stadium and commercial income.
It is also a low-risk appointment as Rose is currently without a club, meaning no compensation is required, but it is one they hope will make an immediate impact next season.
