The 2017 summer transfer window will officially open on Saturday, July 1. This is when players who have signed pre-contract agreements will officially switch clubs. Some transfers will be announced before July 1, but this is the international transfer date.
The window will close on Thursday, Aug. 31 -- almost three weeks after the start of the Premier League campaign and likely to be one week after the start of the La Liga campaign.
The window will close at 11:00 p.m. BST for English clubs. Other leagues are likely to have slightly different deadline times.
