What happened: The Premier League's Key Match Incidents Panel determined that referee Andy Madley should have awarded Liverpool a penalty in the 21st minute after Jurrien Timber pulled Alexander Isak's shirt inside the penalty area. The independent panel voted 3-2 that VAR erred by not recommending an on-field review, though members unanimously agreed the challenge did not merit a red card. Kai Havertz's first-half goal stood as the winner in Arsenal's 1-0 victory at Anfield after video assistant referee Stuart Attwell allowed play to continue.

Why it matters: The retroactive verdict cannot overturn the final score, leaving Arsenal with three points while reinforcing Liverpool manager Andoni Iraola's frustration over fouls going unpunished when attackers refuse to go to ground. The admission also adds to scrutiny surrounding the consistency of video review and shirt-pulling thresholds in decisive head-to-head fixtures.

What to watch: Liverpool continue their regular-season campaign seeking to make up ground in the table, while league officials face renewed pressure to align VAR intervention thresholds.
