Transfer deadline day has become a staple of the football calendar and it's generated a multitude of high-profile deals through the years.
We've delved into the archives and picked out the 10 most expensive transfers made by Premier League clubs on deadline day.
Chelsea set a new British transfer record with the purchase of Enzo Fernandez from Benfica at the end of the January transfer window in 2023.
Fernandez agreed to an eight-year deal and the Argentine has since featured under three different managers at Stamford Bridge: Graham Potter, Mauricio Pochettino and now Enzo Maresca.
Antony became the fourth most expensive signing in Premier League history at the time Manchester United struck a deal with Ajax for a total fee of £85m.
The winger arrived at Old Trafford with a glowing endorsement from Erik ten Hag following his stint in Amsterdam, though it's fair to suggest he's failed to live up to those expectations and the extortionate price tag.
Purchased in the final hours of the 2018 winter transfer window, Pierre Emerick-Aubameyang arrived at Arsenal following a clinical spell with Borussia Dortmund and he carried that form over into the Premier League.
The Gabonese striker shared the Golden Boot in 2018/19 and scored 92 goals in 163 appearances for the Gunners before joining Barcelona in 2022.
Sourcing a replacement for a player of Ilkay Gundogan's calibre is never easy and Manchester City turned to Matheus Nunes after an impressive debut season in the Premier League with Wolves.
Joining on deadline day in September 2023, the Portuguese central midfielder endured a bit-part role as the Citizens were crowned Premier League champions for a fourth consecutive year.
It was a deal that sent shockwaves around the world as Chelsea prised Fernando Torres from Liverpool at the end of the 2011 January transfer window in what was a British record fee.
Torres had a glittering spell at Anfield, scoring 81 goals in 142 appearances for the Reds but he failed to replicate those dizzying heights at Chelsea. It was not all doom and gloom; he scored the pivotal goal against Barcelona that sent the Blues on their way to the UEFA Champions League final in 2012.
After pursuing him for most of the summer and with the bank replenished following Harry Kane's departure to Bayern Munich, Tottenham splashed the cash on Nottingham Forest winger Brennan Johnson on deadline day in September 2023.
Signing a six-year deal, Johnson delivered 15 goal contributions in the Premier League in his first season with Spurs.
Acquired in the final hours of the 2020 summer transfer window, Thomas Partey was a statement signing in the early phase of Mikel Arteta's tenure at Arsenal.
He was instrumental in helping the Gunners to re-emerge as title candidates in the 2022/23 Premier League season and remains on the books at the Emirates Stadium, despite a prolonged injury absence last term.
The one that got away from Pep Guardiola.
Making the bold decision to depart Manchester City in pursuit of regular first-team football, Cole Palmer joined Chelsea in a deadline day switch and has since taken the Premier League by storm.
Netting 22 goals and registering 11 assists in his first campaign at Stamford Bridge, Palmer bagged the PFA Young Player of the Year award and the best is yet to come from the Wythenshawe-born sensation.
Arsenal were desperately searching for a marquee signing in the summer of 2013 - their iconic £40,000,001 bid for Luis Suarez failed to bear fruit - and in the dying embers of deadline day, they proudly announced the superstar arrival of Mesut Özil from Real Madrid.
We were treated to countless moments of divine artistry from Özil during his seven years with the Gunners, though there's always been a lingering sense of disappointment concerning his stint in north London.
"Tony Martial he came from France, English press said he had no chance..."
Anthony Martial was once the most expensive teenager in world football after Manchester United signed him in a deadline day deal from Monaco for an initial £36m in 2015.
He made an immediate impact with a goal against arch-rivals Liverpool on his debut and other than the 2019/20 campaign in which he scored 23 goals, it never really got better than that.
Martial departed Old Trafford this summer after a nine-year stint with the club.
