List of Spanish football transfers summer 2010
The summer transfer window opened on 1 July 2010, although a few transfers took place prior to that date. The window closed at midnight on 31 August 2010. Players without a club could have joined one at any time, either during or in between transfer windows. Clubs below La Liga level could also have signed players on loan at any time. If need be, clubs could have signed a goalkeeper on an emergency loan, if all others were unavailable.
