Liverpool reported rule break in derby explained

Substitutions rule explained clearly

Under Premier League regulations, managers are permitted five substitutions, but crucially these must be executed within three separate windows, excluding half-time. It is a rule designed to maintain rhythm and prevent constant disruption.

Arne Slot, operating within those constraints, used his bench assertively. Two earlier changes had already been made individually in the second half. That left one final window for tactical intervention. In the 84th minute, Jeremie Frimpong and Alexis Mac Allister were introduced together, a conventional use of that final opportunity.

Kerkez’s arrival followed shortly after, and this is where confusion took hold among Everton fans. On the surface, it appeared to be a fourth window, something not permitted under the laws. But the context matters, and in football, context often dictates interpretation.

Kerkez moment and Everton fans reaction

Kerkez entered the match while play was halted due to Jarrad Branthwaite’s injury. The game had not restarted between the earlier substitutions and his introduction. That detail is decisive.

Because the stoppage was continuous, all three changes, Frimpong, Mac Allister and Kerkez, were legally grouped within a single substitution window. There was no breach, no technical sleight of hand, simply an astute reading of the regulations in real time.

Still, Everton fans voiced frustration, particularly on social media, where the optics of the situation suggested something irregular. It is understandable. Football thrives on immediacy, and when substitutions occur in quick succession, the distinction between windows can feel blurred. Yet the rulebook is clear, and Liverpool operated within it.

Tactical edge and broader implications

What stands out is not controversy but competence. Slot’s handling of substitutions reflected a manager alert to both opportunity and detail. The injury stoppage became a tactical hinge. Where others might hesitate, Liverpool acted, refreshing key areas of the pitch without conceding structural balance.

Kerkez’s involvement, though brief in minutes, symbolised that awareness. Fresh legs, defensive assurance, and a subtle shift in momentum all arrived at once. In matches of this intensity, marginal gains often decide outcomes.

The original source of this analysis, Liverpool.com, framed the episode succinctly. It noted that “because the game had not restarted between Mac Allister and Frimpong being brought on, and then Kerkez’s introduction, all three changes are considered to have been made in the same window.” That line alone dissolves much of the debate.

Slot himself struck a measured tone afterwards, reflecting on a season shaped by limitations and resilience. “Throughout the season, all these games with all these games and the limited players available have hurt and cost us quite a lot of points,” he said. “But today is definitely a day for the fans to be happy.”

In the end, this derby will be remembered for its late goal and its emotional swing. The noise around substitutions will fade, as it often does, replaced by the enduring fact of Liverpool’s win and their tightening grip on a top-five finish.
