The international break: why the league stops and clubs must release

The league stops, the weekend fixture list empties and the question comes round again. The answer is not in the domestic league's rulebook. It is in FIFA's international match calendar and in Annexe 1 to the Regulations on the Status and Transfer of Players, in the January 2025 edition. Article 1, paragraph 1 of that annexe states that clubs are obliged to release their registered players to the representative teams of the country for which the player is eligible to play on the basis of his nationality, if they are called up by the association concerned. The same paragraph shuts the door on private deals: any agreement between a player and a club to the contrary is prohibited.

It is worth noticing who the rule binds. It binds the club, not the league. No FIFA regulation orders a domestic championship to stop; the league stops because playing on would mean playing without the players who have been called up. FIFA publishes the international match calendar for periods of four or eight years, after consulting the relevant stakeholders, and it lists every international window in that period (article 1, paragraph 3). Outside those windows, and outside the final competitions covered by the calendar, there is no obligation to release anyone at all (article 1, paragraph 6).

The window that doubled in size

The standard definition sits in article 1, paragraph 4: an international window in men's football is a period of nine days starting on a Monday morning and ending on Tuesday night the following week, reserved for representative teams' activities, with a maximum of two matches per team. Matches may be scheduled from the Wednesday onwards, provided a minimum of two full calendar days are left between them. Item i of the same paragraph carries the exception that redrew the map: since 2026, the September and October window has run as a single period of 16 days, with a maximum of four matches per team.

In practice, September and October stopped being two breaks and became one. FIFA's men's international match calendar, in the version dated April 2026, sets the window from 21 September to 6 October 2026 with four matches allowed, and repeats the shape to the end of the cycle: 20 September to 5 October in 2027, 18 September to 3 October in 2028, 24 September to 9 October in 2029 and 23 September to 8 October in 2030. Each one opens on a Monday and closes on a Tuesday. From 2027 to 2030 the year holds four windows, not five. Matches within a window must still be played on the territory of the same confederation, with two ways out: intercontinental play-off matches and, where at least one of the two matches is a friendly, venues in different confederations, provided they are no more than five hours of flight and two time zones apart (article 1, paragraph 5).

The last column is not written as a number anywhere in the regulations. It follows from article 1, paragraph 7. A player must be released and start travelling to join his representative team no later than Monday morning, and must start travelling back to his club no later than the Wednesday morning after the window ends. In a nine-day window that means ten days away from the club; in the 16-day one, seventeen. For a final competition, release starts on the Monday of the week preceding the week the tournament begins and runs until the morning after his team's last match. Associations must inform the club in writing of the outbound and return schedule ten days before the release period starts (article 1, paragraph 9), and club and association may agree a longer period or different arrangements (article 1, paragraph 8).

Who picks up the bill

Article 2, paragraph 1 is blunt: clubs releasing a player under this annexe are not entitled to financial compensation. The association calling the player up bears his travel costs (paragraph 2), and the wages keep coming out of the club's account, as FIFA's own technical bulletin on the Club Protection Programme acknowledges when it notes that the club usually remains obliged to pay the player's salary under the employment contract. One exception was built outside the annexe: for the 2026 World Cup, FIFA announced on 5 June 2026 a Club Benefits Programme worth USD 355 million, with USD 100 million reserved for clubs that released players for the qualifiers, roughly USD 2,360 per player per match across 905 matches, and USD 250 million for clubs with players at the final tournament, starting from around USD 5,000 per player per day.

The insurance, though, belongs to the club. Article 2, paragraph 3 makes the club with which the player is registered responsible for his cover against illness and accident throughout the release period, extending to any injuries sustained in the international matches he was released for. Paragraph 4 supplies the counterweight: if a professional suffers, during his release for an international A match, a bodily injury caused by an accident and is temporarily totally disabled as a result, the club is indemnified by FIFA. The Club Protection Programme technical bulletin, for the period from 1 January 2023 to 31 December 2026, sets the limits: compensation only where the temporary total disablement lasts more than 28 consecutive days, calculated on the player's fixed salary, up to EUR 20,548 per day, payable for a maximum of 365 days, capped at EUR 7.5 million per player per accident, with an aggregate limit of EUR 80 million per year.

And if the club says no

The regulations do not treat refusal as an option; they treat it as a breach. The association must notify the player in writing at least 15 days before the first day of the window, with the club informed at the same time, and the club must confirm the release within the following six days (article 3, paragraph 2). The player, for his part, is obliged to respond affirmatively when called up by the association he is eligible to represent (article 3, paragraph 1). If a called-up player is not released, article 5 strips the club of any benefit from saying no: unless the association agrees otherwise, he is not entitled to play for his club during the period for which he should have been released, plus an additional five days. A claimed injury can be tested, because article 4 lets the association require a medical examination by a doctor of its choice, which the player may ask to undergo on the territory of the association where he is registered. Violations of the annexe go to the FIFA Disciplinary Committee, judged under the FIFA Disciplinary Code (article 6).

The rule cuts both ways. A released player must resume duty with his club no later than 24 hours after the end of the release period, or 48 hours if the representative team's activities took place in a different confederation (article 1, paragraph 9). If he does not, the club may ask the Players' Status Chamber of the Football Tribunal to shorten his next release by two days in the case of a window, or five days in the case of a final competition (article 1, paragraph 10). Where the violation is repeated, the same chamber may impose a fine, cut the release period further, or ban the association from calling that player up for subsequent representative-team activities (article 1, paragraph 11). Which is why the international break is not a favour traded between club and country: it is an exchange written into the regulations, with a sanction waiting on each side of the line.

How long the league actually stops

The regulations say sixteen days, and that is the window. What a supporter feels is something else: release starts earlier and ends later, and each competition fits its round wherever it can. Measuring the gap between two match days across the 26 competitions in our archive, this window's stoppage runs from eleven to forty-eight days, and four competitions never stop.

The table answers what the regulations cannot: the competitions that stop longest were already idle. European club competitions carry their own gap between stages, and the window falls inside it. The forty-eight days in the Conference League are therefore two things added together, not the effect of call-ups. In domestic leagues the figure tightens: eighteen or nineteen days, almost always back on the 9th or the 10th. And four competitions keep playing: Brasileirão Série B, LaLiga 2, J2 League and the FA Cup, the last with the cup round England tends to slot in right here.

The three stoppages are similar in length and different in kind, and that is the useful reading: the international window is calendar, winter is weather and the World Cup is an event. The middle row rewards a second look. Germany's winter break has shrunk across the archive: forty-six days in 2007/08 and eighteen in 2025/26. And this year's September window runs eighteen days, against eleven or twelve in every season from 2007 to 2025. The calendar tightens from both ends. Measured on 25 September 2026 across 176,347 matches from the 26 competitions in our archive; a stoppage is the gap between two match days in the same competition, and the 2020 and 2021 seasons appear compressed by the pandemic.
