The transfer window in Spain will close on 1 February

No, the transfer window in Spain does not close on 31 January. It is common to talk about the winter transfer window only in the first month of the year, but it closes on 1 February 2024.
FIFA regulations stipulate that in Spain, in both men's and women's football, the winter transfer window in Spain runs from 2 January to 1 February.
The closing date has not been moved back from Wednesday to Thursday in the last few days, but since the start of the season, FIFA has given the previously established dates.
Where it has changed among the big leagues in Europe is in France, which is in line with the closure of the other top-level competitions on the Old Continent.
Likewise, the transfer window in the Netherlands, with top teams such as Ajax, PSV and Feyenoord, has also been moved to the first day of February.
