Iraola's 'Ruthless' Philosophy: Keeping 21-Year-Old Jacquet for Full 90 Despite Yellow Card

I have written hundreds of xG analysis tables on intercity buses across the Mekong Delta, where 3G signals flicker and football is the only thing connecting me to the outside world. But never have I seen a tactical decision so simple yet so subversive of traditional young player management philosophy — the way Andoni Iraola kept Jeremy Jacquet on the pitch until the final minute, despite the defender receiving a yellow card in the 52nd minute. Not instinct. Not recklessness. But a cold calculation with inputs of age 21, a yellow card, and 34 minutes remaining in a match Liverpool were already leading 2-0. On October 19, 2026, at Portman Road, Iraola's side defeated Ipswich Town 2-0. Alexander Isak scored both goals. But the real story wasn't in the scoreline. It was in the decision of a Spanish manager to let a 21-year-old defender — who had just joined from Rennes in the summer — play the full 90 minutes, despite the risk of a second yellow and accumulated fatigue. I have followed many Liverpool matches under Jurgen Klopp, then Arne Slot, and now Iraola. What I've realized after nearly three decades in the stands or by the screen is: every manager has their own mantra for managing young players. Klopp used emotion. Slot used structure. But Iraola — he uses pain. His post-match words were brutally concise: "He has to suffer and go through those periods." No sympathy. No sheltering. No comforting "you did great, be more careful next time." Immediately, the English football media split into two camps. One praised this as Iraola's tactical vision. The other worried about the harsh treatment of a young player, potentially causing injury or shattering confidence. But I — someone who wrote xG on paper before anyone called it "big data" — saw a completely different numbers table behind this decision. Before the Ipswich match, Jacquet had played 69 minutes against Newcastle and 76 minutes against Nottingham Forest. Those were matches where Liverpool had to rotate personnel due to fixture congestion. The issue wasn't how long he could play — but how far he could endure in a genuinely grueling match. Iraola didn't need a perfect defender. He needed a defender who could endure when everything was against him. The yellow card in the 52nd minute came from a high boot on Emersonn. It wasn't an intentional dangerous tackle, but it showed Jacquet was still learning to control his intensity in the Premier League — where in Ligue 1, he might have been forgiven for his superior physicality. In England, every challenge is calculated, every tackle analyzed, and every referee's decision can change the match. But Iraola didn't substitute him. He let Jacquet continue playing, continue enduring, continue learning in real fire. I recall the 2010s, when I analyzed matches of several V.League clubs and noticed that Vietnamese coaches typically substituted young players too early when they made mistakes or received cards. Why? To protect the player's mentality. But what was the result? Players at 25 still didn't know how to handle pressure in the final 15 minutes, because they had never faced it alone. Iraola understands this. He understands that football isn't just about skill — but about the ability to endure when everything goes wrong. And Jacquet didn't disappoint him. He completed 90 minutes. Kept a clean sheet. And crucially, he delivered an accurate vertical pass to Florian Wirtz — a progressive contribution showing he wasn't just defending but creating attacking opportunities from the back. That's why I call this decision "ruthless but deliberate." It wasn't the cruelty of someone who enjoys tormenting players. It was the ruthlessness of a skilled craftsman — knowing that iron must be tempered in fire to become strong, and knowing exactly when to increase the heat. But this is where I must acknowledge the limits of analysis. I don't have detailed fitness data on Jacquet. I don't know how Liverpool's medical team assessed injury risk when he continued playing with a yellow card. I only know that in football, every decision has two sides — and the fact that Jacquet completed 90 minutes doesn't guarantee this strategy will succeed in the next match. This season, Liverpool must compete in the Premier League, Champions League, and possibly the FA Cup. That's the schedule of a big club wanting to compete on all fronts. And that's why Iraola's decision wasn't just about Jacquet — but about the entire rotation system he's building. Before the Champions League match against Atletico Madrid, Iraola needed to know who could play 90 minutes without collapsing. He needed to know who could endure when a yellow card hung over their head. And he needed to know who could maintain defensive stability — where Virgil van Dijk, Ronald Araujo, and Milos Kerkez were forming a three-centre-back partnership requiring perfect connection. I've seen many teams fail because they weren't "ruthless" at the right time. They protected young players by keeping them on the bench. Then when needed most, those players had no experience to step onto the pitch and fight. They had been protected from pain — but also stripped of the opportunity to learn how to defeat pain. This is the lesson I've drawn from years of following youth football in Vietnam. We often talk about developing talent, but forget that talent only develops when challenged. And the greatest challenge isn't training — but real competition, under real pressure, with real consequences. Jacquet passed that test on the evening of October 19. He wasn't perfect — the high boot in the 52nd minute showed he still needs improvement. But he completed 90 minutes. And in modern football, that is a story of growth faster than any fitness drill. Iraola could be wrong. Jacquet could get injured in the next match. Liverpool could lose to Atletico Madrid. But one thing I'm certain of: if Iraola continues developing Jacquet this way, he will become a top centre-back — not because he was protected, but because he learned to protect himself in the fire. And that, in my view, is the correct philosophy for managing young players — however ruthless it may appear to outsiders. I call this philosophy "the art of controlled endurance." And Iraola just showed he's a master of it.
