As Iraola swaps the south coast for Anfield, his long-serving fitness coach has opened up on what made the journey work.
De la Torre sums up his colleague in four words: honesty, sincerity, humility and respect - a description he suggests explains why a project many doubted in 2023 became the most successful spell in Bournemouth's history.
Iraola's first season began with three draws and six defeats, leaving the club bottom of the table with just three points from ten games, before a 2-1 win over Burnley changed the trajectory entirely.
"Respecting the timeline needed for a team - or even a club - to undergo a transformation like this has been crucial," De la Torre told AS. "Seeing that daily evolution, football-wise and human-wise, is one of the proudest achievements of my career."
What followed was a run of records: 12th in 2023-24 with 48 points, then 9th a year later with 56 points and spells as high as 5th. In Iraola's final campaign Bournemouth briefly sat second in the table and later strung together an 18-match unbeaten Premier League run - including wins over Tottenham, Liverpool and Manchester City - to secure Europa League qualification for the first time in the club's 127-year history.
"The key is building a game model and team identity where players truly believe in the coach's idea," De la Torre explained. "Beyond results, I'm proud to have been part of a group that never stopped believing, competing, and improving."
That belief extended to results against the traditional elite.
"He builds brave teams, capable of believing they can beat anyone - even going a full round unbeaten, something only Arsenal, Manchester City, and Chelsea had ever done," De la Torre said of Iraola's approach.
Much of the work went into rebuilding a squad repeatedly stripped of its best performers, with Dominic Solanke, Illia Zabarnyi, Dean Huijsen, Antoine Semenyo, Dango Ouattara and Milos Kerkez all sold for significant fees.
"Rebuilding means investing huge amounts of time teaching players a new work system and game model," De la Torre said. "The ones who grow the fastest usually play a ton of minutes and stay available all season. When they leave, you lose robustness and key pieces who already understood the plan."
He was quick to credit the club's recruitment alongside the coaching staff's work on the training pitch.
"The club deserves enormous credit for identifying generational talents with different strengths but perfectly complementary profiles," he said.
Asked to sum up what sets Iraola apart from other coaches who were linked with the Liverpool job, De la Torre did not hesitate.
"He's incredibly intelligent, leads by example, and has a rare emotional stability in such a visceral sport," he said. "From day one, you sense he's different - his ability to read the game and its needs is almost unique. He filters information so players can digest it easily and apply it every week."
De la Torre is following his long-time colleague to Merseyside, where the pair will now attempt to rebuild an identity of a different kind at Anfield.
