It is close to being another record-breaking year of summer spending - and a new high could still be reached on Transfer Deadline Day.
But when are all the deadlines, what rules must clubs comply with, who are some of history's most iconic deadline-day signings - and which moves could still happen?
Here is all you need to know about deadline day - and how you can keep across the action.

Premier League and EFL clubs have until 23:00 BST on Tuesday, 1 September to complete their transfers.
The deadlines for other leagues around the world are:

Fifa rules state a transfer window cannot last more than 16 weeks in a calendar year.
What is a deal sheet?
A deal sheet must be completed by Premier League clubs in the last two hours of a transfer window.
This year, the earliest it can be submitted is 21:00 BST, and must be complete before the 23:00 deadline - giving clubs two hours to finalise required paperwork.
Without all paperwork submitted before 23:00, transfers cannot proceed.
Clubs often leave their transfer dealings to the last minute, and therefore have to submit the form to the Premier League to make sure a move can go ahead.
The deal sheet allows a club to confirm an agreement has been reached and also give themselves more time to submit the remaining documentation.
Can players be signed for free after the deadline?
Players who remain free agents after the closure of the transfer deadline can be signed at any point.
They won't be able to play for their new side immediately - unless there is space in the club's registered 25-man squad - as they have to wait until the next period of registration to come around.
While there is no official deadline that is made public, it is understood the deadline is about a week after the window closes.
How many players can a Premier League squad have?

A Premier League squad list must not contain more than 25 senior players.
This list is published for each club following the closure of the transfer window.
Of those maximum 25 players, no more than 17 can be registered that are not classed as 'homegrown' talent.
As the 25-player rule only applies to senior players, any squad members under the age of 21 at registration cut-off do not count towards the total tally - meaning clubs can register as many under-21 players as they want.
But clubs must otherwise carefully manage the numbers of senior players on the books, or some will be contracted to a team they cannot play for.
Chelsea have previously faced criticism for an oversized squad that had led to the use of a so-called 'bomb squad' - a practice which has since been outlawed by Fifa.
What moves could still happen?
As always, expect a few late twists and turns when it comes to the final day of the window.
There are however plenty of players whose futures remain up in the air and could be set for a late move.
Manchester City midfielder Jack Grealish looks set to return to Everton on loan, with Toffees winger Iliman Ndiaye heading in the opposite direction for £65m.
Chelsea midfielder Enzo Fernandez has also been linked with a reunion with former boss Enzo Maresca at City. Xabi Alonso's side are set to be looking at Monaco's Lamine Camara to bolster their own midfield.
Elsewhere, Atletico Madrid striker Julian Alvarez is of interest to Arsenal and Barcelona and could leave the Spanish capital prior to the window closing.
Liverpool winger Cody Gakpo has been a target for both Spurs and City, although any exit would be dependent on the Reds securing a replacement - which is increasingly unlikely.
Who has been signed on previous summer deadline days?

Perhaps the most dramatic signing of the 2025-26 summer transfer window was Alexander Isak's departure from Newcastle United, joining Liverpool on deadline day and breaking the British transfer record in the process.
Some other memorable deadline-day deals over the years include:
Claude Makelele from Real Madrid to Chelsea (2003)
Wayne Rooney from Everton to Manchester United (2004)
Carlos Tevez and Javier Mascherano from Corinthians to West Ham (2006)
Ashley Cole from Arsenal to Chelsea (2006)
Hugo Lloris from Lyon to Tottenham (2012)
Mesut Ozil from Real Madrid to Arsenal (2013)
Cristiano Ronaldo from Juventus to Manchester United (2021)
Cole Palmer from Manchester City to Chelsea (2023)
