The deals that go down to the wire are usually the most memorable. The frenzied and frantic transfer deadline day has now become legendary for teams pulling off eleventh-hour deals.
When fate and time is on their side, these deals can prove to be business masterstrokes.
Here are the nine greatest transfer deadline day deals in Premier League history.
9. Marouane Fellaini (Standard Liege to Everton for £15m, 2008)
The Belgian powerhouse may not have fully found his feet at Manchester United following a £27m move in 2013, but Everton certainly saw the best of him during his five years at Goodison Park.
After David Moyes signed him from Belgian side Standard Liege, Fellaini was brilliant for the Toffees and played a pivotal role in their progression under the Scottish manager.
Fellaini scored 25 league goals in 141 league appearances for Everton.
8. Ashley Cole (Arsenal to Chelsea for £5m in 2006)
After winning the Premier League twice with Arsenal, Ashley Cole moved across London to rivals Chelsea to join Jose Mourinho's revolution.
In retrospect, for £5m the deal looks like a real coup as Cole went on to cement his place as one of the finest left-backs in the world and found great success at Stamford Bridge in winning a league title, four FA Cups, the Champions League and the Europa League.
Cole made 338 appearances in all competitions for the Blues.
7. Jermain Defoe (West Ham to Spurs for £7m in 2004)
It may not have been the most glamorous signing at the time, but Jermain Defoe quickly became one of the most dangerous marksmen in English football during his time at Spurs.
With Bobby Zamora going the opposite way, Defoe soon made the White Hart Lane faithful forget about the big striker as he scored 61 goals in 170 appearances for the North London side.
Defoe spent two seasons at Portsmouth from 2007-09 before returning to Spurs for an additional six seasons.
6. Claude Makelele (Real Madrid to Chelsea for £16m in 2003)
Thanks to his unrivalled tactical brain and fighting spirit, the Frenchman became a cult hero at Stamford Bridge and a crucial first-team player.
Makelele redefined the holding midfielder role during his career and always provided the team with great balance and security.
The former Real Madrid star spent five successful seasons with Chelsea, making over 140 appearances and winning two Premier League titles.
5. Robbie Keane (Leeds United to Spurs for £7m in 2002)
Robbie Keane built a reputation during his time at Coventry City and was bought by Leeds. However, his predatory instincts attracted admiration from Tottenham and they snatched him up in 2002 when Leeds were in a deepening financial crisis.
For Keane, the rest is history as he went on to become a true Spurs legend. The Irishman spent six goal-laden years at White Hart Lane before a dream move to Liverpool. However, things did not work out for him at Anfield and he has since settled down in the MLS with LA Galaxy.
4. Hugo Lloris (Lyon to Spurs for £8m in 2012)
Hugo Lloris is one of the finest goalkeepers in the world and it is difficult to imagine him being snapped up by Spurs for a mere £8m. The French captain has established himself at White Hart Lane and there are consistent rumours linking him with mega-money moves to PSG, among others.
Lloris has made 83 league appearances for Spurs.
3. Carlos Tevez (Corinthians to West Ham in 2006)
In what became one of the most legendary transfers of all time, Argentine superstars Carlos Tevez and Javier Mascherano landed in East London from Brazilian side Corinthians in 2006.
Although Javier Mascherano did not feature heavily in Alan Pardew's first-team, Carlos Tevez almost single-handedly saved the Hammers from relegation.
Scoring crucial goals, including the winner at Old Trafford on the final day of the season, which confirmed West Ham's status as Premier League survivors, Tevez will always be remembered fondly at the Boleyn Ground.
2. Wayne Rooney (Everton to Manchester United for £25m in 2004)
Spending £25m on a teenager was considered a risk in 2005, as it should have been, but what a success Rooney has proven to be at United.
Now club captain, Rooney has enjoyed a decade of success at Old Trafford and became one of the greatest players in the world.
He has made 459 appearances and scored 224 goals on his way to becoming a true Manchester United legend.
1. Luis Suarez (Ajax to Liverpool for £22.8m in 2011)
Andy Carroll he wasn't. Although Liverpool splashed out more money on the Newcastle striker, it was Suarez that would go on to become one of Liverpool's finest ever players.
In a tenure marred by controversy, Suarez was nevertheless a magician with the ball and scored 82 goals in 133 appearances before moving to Barcelona in 2014.
