The 41st-minute penalty and Nat Phillips' repeating pattern: West Brom lose unbeaten run to Birmingham

Minute 41, The Hawthorns. Phil Neumann delivered a deep cross from the right, and Nat Phillips jumped to contest an aerial ball with August Priske. The West Brom centre-back's elbow made contact with the Birmingham striker's back before both landed. The referee did not hesitate, pointing to the penalty spot. Priske coolly side-footed high to Max O'Leary's left, and Birmingham left The Hawthorns with a 1-0 win.

This was the second successive derby in which Phillips was at fault. Last time, his back pass let in Fer Lopez in a 1-0 defeat to Wolves. This time it was a foul in an aerial duel. Two derbies, two moments, one worrying pattern for Albion's defence.

West Brom lost a 10-match unbeaten home run in the league — their first such streak since James Morrison took charge in February.

Context: a derby shaped in the first half

The opening 20 minutes were open and fast. A mis-hit back pass from Phil Neumann almost cost Birmingham, but goalkeeper James Beadle dashed outside his box, beat Aune Heggebo to the loose ball and cleared. At the other end, Max O'Leary produced a superb reflex save to deny Jay Stansfield's close-range sliding shot.

Albion broke at speed. Heggebo steered a shot against the foot of a post with Beadle beaten. Jhon Solis got his footing wrong after Heggebo's poor clearing header from Alex Cochrane's cross, the Colombian midfielder shinning his effort from 12 yards. Felix Horn Myhre should have put Albion ahead in the 28th minute, heading just over the bar with more than half the goal to aim at. Callum Styles curled a low free-kick around the three-man wall, and Beadle tipped the ball behind.

Then came the 41st minute. Neumann crossed deep, and Phillips jumped half a beat later than Priske.

West Brom and Birmingham share one of the most tense relationships in English football. This fixture is not merely three points; it is identity. In derbies like this, teams often play on emotion rather than reason, and individual mistakes become twice as costly.

Morrison took over the club in February with West Brom needing stability. He built a disciplined defensive block and a home unbeaten run that stretched to 10 matches — the club's best in years. That run had never been tested by the pressure of a derby like this one, and it broke.

Core: dissecting a decision

I have watched this moment several times. Not to argue right or wrong — that belongs to the crowd — but to understand which mechanism produced the decision. Under Law 12 of the IFAB Laws of the Game, a challenge is a foul when it is careless, reckless or uses excessive force. In an aerial duel, the key standards are the position of the arm and the approach of the body.

Phillips jumped later than Priske. When a centre-back jumps late, his body is forced to compensate by reaching out an arm to keep balance. That is physics, not malice. But the law does not measure malice; the law measures consequence. An elbow in an unnatural position during an aerial duel creates an avoidable contact, and under IFAB's current reading, that is a foul.

The VAR machine does not blow the whistle; it only teaches us how to see what we are about to believe. In this situation, VAR had almost no role to play in overturning anything. The on-field decision sat in the zone of subjective judgement, and the foul involved clear contact. There was no clear and obvious error to intervene on.

What is more striking is the contrast between the two halves. In the first half, both teams contested fiercely but the referee kept the rhythm. By the 41st minute, a single moment of lost balance decided the match. Derby football works this way: it does not reward the better team over 90 minutes, it punishes the team that errs at the exact moment.

I always tell younger colleagues not to view a penalty as an event; view it as a chain of decisions. The chain here began with the defensive choice to let Neumann cross freely, continued with Phillips' decision to jump late, and closed with the referee's decision to point to the spot. Every link could have been cut. No link was cut.

In modern football, centre-backs are coached not to reach out an arm when contesting aerially. It is a learnable discipline. But when a player jumps half a beat late — as Phillips did here — survival reflex beats discipline. This is why coaches increasingly prioritise centre-backs who read situations early: they do not need to reach out because they are already in position before the ball arrives.

Priske, on the other side, did exactly what a striker must do: he jumped early, claimed the position, and forced his opponent to react. In aerial duels, the player who jumps first usually controls the contact. That is not luck; it is technique.

Just before half-time, O'Leary had to rescue Albion again, tipping Neumann's fierce downward header over the bar. Four Albion players slid in to block Solis' shot from six yards after O'Leary got a hand to Cochrane's corner.

In the second half, Patrick Roberts — on as a Blues substitute — went down after minimal contact from Chris Mepham and appealed for a penalty, but the referee was unmoved. That was a correct decision under the minimal-contact standard: not enough basis to award a foul in a tense derby. What is interesting is that the same referee awarded a similar contact in the 41st minute, but in an aerial duel, where the human body has no anchor, the threshold for a foul is lower.

Contrarian angle: emotion versus law

There is another reading of this penalty, and I want it stated even though it runs against the wave of outrage in the stands. If Phillips jumped late and his elbow extended as a balancing reflex, then the right question is not whether he intended it. The right question is: should the law punish a physical reflex that the human body cannot fully control?

This is the very issue I have spent years researching. When the Premier League set a record 40 penalties in the 2026/21 season, most coming from IFAB's new handball law, I downloaded all the Opta data on 47 awarded incidents and coded the angle of contact, arm posture and distance myself. The results showed referees tended to penalise when the arm deviated from the natural body silhouette — a concept the law never defines.

The pandemic handball law was a logic accident that its designers failed to recognise. Something similar is repeating in aerial duels. We are punishing the human body for not conforming to a theoretical model no one has ever built.

But — and this is the crucial point — injustice in the design of the law does not make the referee's decision wrong. The referee applies the law that exists. If we want to change outcomes, we must change the law, not blame the person blowing the whistle.

Clear and obvious — how sports law names its own powerlessness.

Takeaway: trends and what must change

West Brom must now look not only at their defence but at how they manage decisive moments. The 10-match home unbeaten run is a genuine achievement, but it was erased by a moment the team could have avoided with better aerial discipline. Phillips made the error, but a defensive system that left him alone against a striker jumping earlier is the root problem.

For Birmingham, Priske proved the value of a striker who knows how to create contact inside the box — an increasingly important skill in modern football, where minor fouls are magnified by technology and rules.

The match closed with O'Leary's foot denying Demarai Gray at the near post, and with Ousmane Diakite sending a long-range drive wide. Barney Stewart's glancing header was tipped over by the keeper from Jimmy-Jay Morgan's cross. Max Bird won the ball high and Stansfield curled straight at O'Leary. Brayann Pereira sliced high and wide after a 40-yard run from inside his own half.

What remains is a question English football will have to answer: will we keep punishing unavoidable physical reflexes, or will we dare to rewrite the law so it reflects the physics of the human body?
