Madrid Derby: Baena's Knee, Ortiz Arias's Silence, and the Grey Zone VAR Cannot Touch

In the fifth minute of the Madrid derby on La Liga matchday seven, Arda Güler collected the ball on the right flank and drove forward. Álex Baena tracked him from behind. One collision was enough to send Güler's slender frame to the turf, his hand reaching for his hip and hamstring. Referee Ortiz Arias pointed for a Real Madrid free kick. No card left his pocket.

The Atlético technical area erupted. Diego Simeone threw his arms up, shouting toward the fallen player, and was booked. Güler, the man who had just been brought down, was drawn into the argument when he responded.

Thirteen minutes later, the same two names met at the same flashpoint. Baena went into Güler again. Ortiz Arias kept his cards where they were. This time the calls for punishment came from Real Madrid's side.

Iturralde González, a former referee who has officiated hundreds of La Liga matches, was blunt on television: it was a yellow card. He stressed that Baena had used his knee from behind to bring his opponent down, an act that had to be punished. He also questioned the decision to book Simeone when several Real Madrid substitutes had risen to protest and should have been treated the same way.

The Madrid derby has never been an ordinary fixture. It is a meeting of two philosophies close in geography and far apart in identity: one side playing a controlled, elegant game that always demands space; the other defined by tightness, contact and a readiness to turn every duel into a fight for emotional control. On matchday seven of La Liga, both teams needed points, and derbies like that are usually settled by the smallest details outside the scoreline.

Arda Güler is the kind of player La Liga defences learn to handle in two ways: tight from the front, or stopped from behind. He does not have the speed of a sprinter; he has timing. The way he releases the ball half a beat late forces defenders to choose between holding position and diving in. Álex Baena belongs to the group of high-energy pressing midfielders trained to break that timing before it takes shape.

In more than thirty-five years of watching football, I have sat in the press area of more than a few derbies. What I learned does not lie in what a referee calls, but in what he does not.

In the fifth minute, Baena drove his knee into the back of Güler's thigh while both were accelerating. This is the detail most viewers miss: a knee from behind, delivered while the opponent is accelerating, strikes the hamstring and ligament area far more broadly than a challenge with the lower leg. The lower leg meets the ball or the leg; the knee, with its smaller contact area and greater compressive force, lands on the hip and the back of the thigh, where most serious football injuries begin.

The laws of the game split fouls into three tiers: careless, reckless, and using excessive force. A leg challenge that wins the ball before touching the player usually falls into the careless tier, with no card. A knee from behind, once the ball has already moved past the opponent, almost always sits in the reckless tier, a yellow card. That is why Iturralde González put it simply: 'That is a clear yellow card.'

Ortiz Arias's problem was not one incident but consistency. He booked Simeone for an excessive reaction while letting similar reactions from the Real Madrid bench go unpunished. He waved away two collisions involving the same pair of players within thirteen minutes. In a derby, that inconsistency has a double effect: it does not stop players from going in hard, and it teaches them that the price of pressuring the referee may be higher than the price of fouling.

In the eighteenth minute, when Baena and Güler collided again, Ortiz Arias still did not reach for a card. Football is the only place where adults are allowed to rage like children without explanation, and also the only place where a wrong decision can drift past in silence, corrected by no one.

The blind spot lies elsewhere, and it belongs to the system rather than to the referee's eyes. Under the current VAR protocol, the video team can only intervene in four categories of incident: goals, penalty decisions, direct red cards, and mistaken identity. A foul at the yellow-card level is not on that list. Every error at the yellow-card tier therefore sits beyond correction, even when it repeats twice in one match, by the same player, against the same opponent.

From an editing desk in Liverpool, I watched the footage three times. The first time to confirm where the knee landed. The second to watch Simeone. The third to watch the people nobody mentions: the Real Madrid substitutes rising from the bench, and Ortiz Arias not turning around to look at them.

One thing gets overlooked in debates like this. People argue about whether a referee was right or wrong, but rarely ask why errors at the yellow-card tier cannot be fixed. A decision that cannot be corrected will not be reviewed, and a decision that is not reviewed slowly becomes the standard. In leagues with high collision intensity, that standard shapes how players choose to challenge: with the leg, or with the knee.

Güler got up in the fifth minute, kept carrying the ball, kept asking for it. He did not change how he plays. Neither did Baena. Neither did the referee.

I no longer chase the ball the way Mbappé does, but I have learned to chase its story. Every matchday that passes is a book closing; the careful reader finds himself inside it. And on the page about the fifth minute of a Madrid derby, the most memorable thing may be a knee, not a goal.
