Premier League clubs have spent more than £1billion over the last decade during the January transfer window.
With the window about to open again, we break down the figures from financial services firm Deloitte and looks at the key deals done.
2007: £60million
A modest outlay, with stand-out deals including Aston Villa shelling out £9.65million to take Ashley Young from Watford and Javier Mascherano's protracted moved from West Ham to Liverpool, which was not completed until well into February.
2008: £175million
The highest disclosed fee was the £15million Chelsea paid Bolton for the services of Nicolas Anelka. Stoke signed Ryan Shawcross from Manchester United for a bargain £1million, Branislav Ivanovic joined Chelsea from Lokomotiv Moscow and Portsmouth recruited Lassana Diarra and Jermain Defoe.
2009: £170million
Tottenham were the big spenders, shelling out a combined £39million to take Defoe back from Portsmouth, Wilson Palacios from Wigan and striker Robbie Keane from Liverpool, while Andrei Arshavin joined Arsenal from Zenit St Petersburg.
2010: £30million
A low-key transfer window was headlined by Adam Johnson's £7million move from Middlesbrough to Manchester City. City also brought in Patrick Vieira from Inter Milan while Stoke secured another bargain by recruiting Asmir Begovic from Portsmouth for £3.25million.
2011: £225million
The biggest-spending January so far saw some of the most high-profile transfers in Premier League history on a frantic deadline day. Chelsea signed Fernando Torres for a record £50million from Liverpool, who splashed out £35million on Andy Carroll and £23million on Luis Suarez. Other big-money moves included Edin Dzeko to Manchester City and David Luiz to Chelsea.
2012: £60million
Two favourite sons returned, with Thierry Henry rejoining Arsenal and Paul Scholes coming out of retirement to play again for Manchester United. The biggest fee was the £10million Newcastle paid Freiburg for Papiss Cisse while Kevin De Bruyne and Gary Cahill both joined Chelsea.
2013: £120million
Liverpool were busy, signing Daniel Sturridge from Chelsea for £12million and Philippe Coutinho from Inter Milan for a bargain £8.5million. Wilfried Zaha's £10million move to Manchester United from Crystal Palace proved less successful, as did QPR's decision to spend £12.5million on defender Christopher Samba. John Stones joined Everton from Barnsley for £3million.
2014: £130million
Manchester United broke their transfer record to sign Juan Mata from Chelsea for £37.1million while Chelsea invested £44million in Nemanja Matic, Kurt Zouma and Mohamed Salah. Leicester paid a rather smaller fee to Le Havre for Riyad Mahrez - reportedly just £400,000.
2015: £130million
Wilfried Bony's £28million move from Swansea to Manchester City topped the spending charts, while Juan Cuadrado's equally ill-fated transfer from Fiorentina cost Chelsea £23.3million. Defoe returned to the Premier League, joining Sunderland, while Zaha headed back to Palace from Old Trafford. Tottenham signed Dele Alli in a bargain £5million deal from MK Dons.
2016: £175million
Newcastle splashed the cash in a bid to avoid relegation, spending £12million on Jonjo Shelvey from Swansea and a similar amount to take Andros Townsend from Tottenham. Stoke broke their transfer record with the £18.3million capture of Gianelli Imbula from Porto and Everton paid £13.5million for Oumar Niasse, who a year later has started just a handful of matches.
