Transfer deadline day is, without question, the most frantic day of the football calendar - in the Premier League at least.
Clubs have all summer to conduct their business, but there's something about a deadline which encourages procrastination.
In the final 24 hours chief executives and managers wake from their slumbers and panic, conducting all their business in a frenzy as the clock ticks towards 23:00 BST.
Sometimes it pays off, sometimes it doesn't, but it is without doubt fun to watch.
GMF looks back at deadline days past, and remembers some of the masterstrokes and some of the clangers that define 24 mad hours of caffeine fuelled negotiations.
Wayne Rooney - Everton to Manchester United | August 31 2004
An 18-year-old Wayne Rooney swapped Goodison Park for Old Trafford in a £20m move. The teenage sensation had just taken Euro 2004 by storm, and David Moyes knew it would be a struggle to keep hold of his young star.
His United debut underlined his potential, a stunning hat-trick putting paid to Fenerbahce in the Champions League. Eight years later and Rooney is United's star striker, and England's one world-class player.
Carlos Tevez & Javier Mascherano - Corinthians to West Ham | August 31 2006
The Argentinian pair turned up to Upton Park and the football work looked on, completely stunned. Tevez had been linked with Europe's top clubs while Maschereno's stock was rising, but no-one predicted they'd end up in east London.
Mascherano failed to settle, but Tevez helped save West Ham from relegation - scoring the winner at Old Trafford on the final day. Since then, both have had successful careers, and won trophies aplenty at Manchester City and Barcelona.
Jermain Defoe - Tottenham to Portsmouth | 2008
A huge coup for the south coast club, largely thanks to the pulling power of then-manager Harry Redknapp. Defoe formed a lethal partnership with Peter Crouch, before Redknapp took Defoe with him to Spurs.
Danny Murphy - Tottenham to Fulham | 2007
The former-Liverpool midfielder was cast aside at White Hart Lane, but, signed by Fulham, the peerless midfielder extended his career to great effect, helping the Cottagers to a Europa League final under Roy Hodgson.
Marouane Fellaini - Standard Liege to Everton | 2008
The rangy Belgian arrived at Goodison Park for a club record £15m fee, but David Moyes will be glad he broke the bank to sign the midfielder.
Initially deployed as a midfield enforcer, Fellaini was effective if unspectacular, but a subtle prod further up the pitch has paid off, and the Belgian has given Premier League defenders nightmares ever since.
Robinho - Real Madrid to Manchester City | 2008
The ultimate deadline day deal. Sheikh Mansour arrived at Manchester City ready to fund a revolution but his initial steps were some way off the mark.
Robinho was the £32.5m marquee signing, and enjoyed a reasonable first season at the Etihad. But the Brazilian failed to settle in Manchester and was soon back off to the sunnier climes of Santos on loan.
Andy Carroll - Newcastle to Liverpool | 2011
The England frontman will forever, unfortunately, be referred to as the £35m Andy Carroll. Liverpool's gamble didn't pay off, Carroll's name on the teammate was rare, a Carroll goal even rarer.
With a new manager in place in the form of Brendan Rodgers, Carroll was deemed surplus to requirements and has been shipped off to West Ham on loan.
Afonso Alves - Heerenveen to Middlesbrough | 2008
The 2008 transfer windows were not happy times for Brazilian strikers. While Robinho found himself in Manchester, international compatriot Afonso Alves turned up in Middlesbrough for £10m.
Boro's then manager Gareth Southgate justified the club record fee by pointing indignantly at the Brazilian's track record in front of goal - an impressive 45 in 38 for Heerenveen. But, sadly for Boro, Alves could only muster 10 in 42 before scarpering to Qatar.
Benni McCarthy - Blackburn to West Ham | 2010
At first glance, signing a proven Premier League goalscorer for £2.5m looks like a bargain. But Benni McCarthy seemed positively allergic to the nets at Upton Park and departed zero goals later after West Ham terminated his contract for £1.5m.
Paul Konchesky - Fulham to Liverpool | 2010
Roy Hodgson's Liverpool nightmare began just as the ink dried on the Paul Konchesky deal. Hodgson wanted his loyal left-back alongside him at Anfield, but Konchesky failed to gain the support of the Reds faithful. Shipped out on loan to Championship side Nottingham Forest.
