The revised format and scheduling of the FIFA Club World Cup (CWC) has posed a unique challenge for the summer transfer window, as the tournament clashes with the usual mid-June opening, creating complexities around player registrations and transfer dealings—particularly for clubs involved in the competition, such as Chelsea and Palmeiras.

To address this issue, FIFA announced earlier this season that football associations would be permitted to introduce two separate summer transfer windows. This provision ensures that teams competing in the CWC, as well as other clubs seeking to maintain competitive balance, can conduct business before the tournament begins while still allowing the transfer window to remain open until the end of August, in line with tradition.

Under FIFA regulations, transfer windows cannot exceed a combined duration of 16 weeks. Typically, this allocation consists of a four-week winter window and a twelve-week summer window. However, if the 2025 summer window were to open on 1 June, a continuous twelve-week period would not be sufficient to extend until the end of August.

As a result, rather than closing the window earlier than usual, the Premier League has chosen to align with most of Europe, where football authorities have already confirmed the adoption of a split summer window, following FIFA’s new provisions.

In an official statement released today, the Premier League confirmed the dates for the 2025 summer transfer window:

"The window will open early, between Sunday 1 June and Tuesday 10 June, due to an exceptional registration period relating to the FIFA Club World Cup.

It will then reopen on Monday 16 June and close on Monday 1 September."

This arrangement is expected to enable clubs to register players, such as Dário Essugo, for the Club World Cup, which commences on 14 June. Furthermore, FIFA will permit clubs to register additional players for the knockout stages of the tournament later in the month. Interestingly, under FIFA regulations, clubs may also be allowed to sign players solely for the duration of the competition, potentially leading to some unusual transfer scenarios.
