Serie A 2026-27 begins on Saturday 22 August. The summer transfer window closes on 1 September at 8pm. In between there are ten days and two rounds of football played by squads nobody can yet call complete. This is not a scheduling flaw specific to this year: it is the normal shape of the European calendar, and it is worth looking at what it produces.

Two calendars that do not talk
Fixture dates and window dates come from different tables. The calendar depends on the windows reserved for international football, on European competitions and on broadcasting distribution. The transfer window is set by the federations within internationally agreed limits, and in recent years the main leagues have chosen to close it on the same day so that nobody gains an advantage by staying open longer.
The result is that the season starts while the teams are still moving objects. That is not an administrative detail: it changes the work on the pitch.
What cannot be drilled
A coach prepares the opening round knowing three things, and not knowing a fourth. He knows who is in the squad today, who has worked with him in pre-season, who is physically ready. He does not know who will be there in two weeks.
This weighs most on unit automatisms, the part of the game that requires the most repetition and the least talent. The defensive line is the clearest example: the distance between the centre-backs, the moment the line steps up, who calls the offside trap are things built over weeks of work with the same group of four or five men. If one of those five can still be sold, drilling that chain is an investment at risk.
The same applies to the goalkeeper, who is the apex of the defensive chain and at the same time the first builder. Changing him days before kick-off means the defenders will have to learn on the move at what distance to lay the ball back and how quickly the new team-mate releases it.
What gets drilled instead
Teams that live this phase consciously move the work onto three things that do not depend on individuals. The first is structure: the distances between the units, the shape of the team in and out of possession, which hold whoever the interpreter is. The second is set pieces, where what is needed is clear individual tasks rather than long-term understanding. The third is transition, which asks for quick reactions more than memorised patterns.
That is why, statistically, opening rounds look little like the rest of the season. There are more goals from set pieces, more games decided by incidents and fewer teams recognisable in their passing. It is not randomness: it is what remains when collective work has not had time to settle.
The cost nobody books
Then there is the human part. A player who knows he is on the market plays the opening round in a particular mental state: if he gets injured the move collapses, if he plays badly he loses value, if he plays well he can be sold better. Asking him to be the man who commands the defensive line during those two weeks is asking for something his head is not in a position to give.
The flip side concerns those who arrive. A signing who joins after the first round is not paying a physical price, which is recovered in a few weeks. He pays a tactical and relational one: he has not done pre-season, does not know his defensive partner’s calls, and walks into a group that has already set its hierarchies.
How to read the first two rounds
The practical consequence, for anyone watching, is simple: late August results deserve less weight than the table gives them. A team that loses its first two games with four starters still to integrate is not a team in crisis, and its real season opener is probably the third round.
The opposite holds too. A club that closed its business early and could work with the same group all through August starts with a real advantage, but one with a short expiry date. After ten rounds that margin is spent, and only the players remain.

Frequently asked questions
When does Serie A 2026-27 start and when does the window close?
The opening round is played between Saturday 22 and Monday 24 August 2026, with Como against Udinese and Inter against Monza kicking things off. The Italian summer window closes on 1 September at 8pm. Two rounds fall in between.
Does this only happen in Italy?
No. The main European leagues have harmonised the closing date on 1 September, varying only the local times. The Premier League starts on 21 August and closes its window on the same day as the others, while Ligue 1 begins on 23 August.
Why does the season not wait for the window to close?
Because the two calendars answer different needs. Fixture dates depend on broadcasting deals, international breaks and European competitions, while the window is set by the federations within limits agreed internationally.
What changes in practice for a coach?
He has to prepare competitive matches knowing that some starters may leave and some signings will arrive once work has begun. It changes which automatisms are worth drilling, how the dressing room is handled and how much weight to give the first two results.
Is a player who arrives after the start at a disadvantage?
Usually yes, but not for physical reasons. The delay is tactical and relational: he has not gone through pre-season with his new team-mates and has to learn the movements while everyone else has been repeating them for weeks.
