The protracted summer 2020 transfer window has now ended, with teams now having to wait to January if they want to improve their squads.
Football has been hit hard financially by the coronavirus crisis, with spending on transfers no doubt down on where it would have been under normal circumstances.
Still, there were still a few deals that were completed for huge fees. Let's have a look at the 10 most expensive.
1. Kai Havertz: Leverkusen to Chelsea - £72m
Chelsea were under a transfer ban last season which meant they were unable to sign any players. However, they have emphatically made up for lost time by spending over £220m this summer, the most expensive of which being Kai Havertz.
The fee was continually negotiated between the clubs, but Leverkusen eventually accepted the £72m up front with significant add-ons set to come into play further down the line for the German playmaker who is generally regarded as one of the finest products of his generation.
2. Arthur: Barcelona to Juventus - £64m
In one of the strangest transfer deals in recent memory, Barcelona allowed talented midfielder Arthur to leave for Juventus for £64m while signing 30-year-old Miralem Pjanic in return for just £10m less.
The Brazillian hasn't made much of an impact yet on the Bianconeri, but given time he should be an excellent addition for Andrea Pirlo's new-look side.
3. Victor Osimhen: Lille to Napoli - £63m
Victor Osimhen became a hot transfer property in Europe following his performances for Lille in the 2019/20 campaign. While nearly every elite club in England were linked with his signature, most notably Liverpool, Napoli were proactive in their pursuit of the Nigerian and quickly shelled out the £63m asking price.
He is yet to score for his new club, but looked sharp and engrained in Napoli's way of playing in the big 6-0 win over Genoa.
4. Ruben Dias: Benfica to Man City - £61m
Even though the deal was in the works beforehand, Man City's 5-2 embarrassment at home to Leicester further emphasised their need for a commanding centre-back, most likely to partner Aymeric Laporte.
Pep Guardiola has a shoddy record of signing defenders, so there is an element of a Hail Mary about this one. Should it not work out, and City fail to land any silverware this season, could it really be curtains for the legendary Spaniard?
He can't throw money at the defensive issues forever...
5. Miralem Pjanic: Juventus to Barcelona - £54m
Miralem Pjanic is a very good player and has been for a while, but Barca had already agreed to this odd deal involving Arthur prior to the 8-2 demolition from Bayern in the Champions League.
Between that and Pjanic signing they got a brand new head coach in Ronald Koeman. Would that deal have been done with the Dutchman in charge? Considering he spent the entire window trying to sign Gini Wijnaldum from Liverpool, probably not.
6. Timo Werner: RB Leipzig to Chelsea - £48m
Chelsea caught everyone by surprise when they signed one of the best centre-forwards in Europe in the 2019/20 campaign when it seemed previously like he had been destined for Liverpool.
Jurgen Klopp ultimately decided against signing his compatriot which opened the door for Chelsea to trigger his £48m release clause. He is yet to score in the league for the Blues, but has impressed nonetheless.
Once Frank Lampard actually plays him up front, he should start finding the back of the net again.
7. Ben Chilwell: Leicester to Chelsea - £45m
Even before the huge spending spree which Chelsea went on, their number one priority in the summer window was the purchase of a new, starting left-back.
In Lampard's first season as boss, neither Marcos Alonso nor Emerson Palmieri made the position their own.
Nicolas Tagliafico, David Alaba, and Sergio Reguilon were some of the names tipped to make the switch to Stamford Bridge, but Chelsea eventually went homegrown with Chilwell, who developed into one of the Premier League's best full-backs while under Brendan Rodgers at Leicester.
8. Mauro Icardi: Inter to PSG - £45m
Mauro Icardi had already been on loan at PSG from Inter the previous season and impressed enough for the Ligue 1 champions to make the move permanent, even if head coach Thomas Tuchel and director of football Leonardo reportedly butted heads over the deal.
For a player of his quality, £45m isn't too high a price if he can continue to bang in the goals.
9. Thomas Partey: Atletico to Arsenal - £45m
In the final minutes of transfer deadline day, Arsenal secured the signing of Thomas Partey from Atletico Madrid after triggering his £45m release clause.
10. Nathan Ake: Bournemouth to Man City - £41m
After Bournemouth were relegated after the conclusion of the 2019/20 season it seems inevitable that star defender Nathan Ake would leave the club.
In his attempts to rebuild a leaky defence, Guardiola would sanction the £41m purchase of Ake.
However, with the arrival of Dias, and with Laporte back fit, could we actually see him moved out to left-back for the foreseeable future?
Bonus:
Leroy Sane: Man City to Bayern - £40.5m
How to improve on near enough perfection...
Bayern swept aside all competition last season to win the treble of the Bundesliga, the DFB-Pokal, and the Champions League.
Their attacking prowess was so devastating destroyed Spurs, Chelsea, and Barcelona all in the one season.
It takes someone special to improve that frontline, but luckily they managed to recruit one of the most devastating wingers in the world on his day in Leroy Sane, and for the cut-price fee of just over £40m due to him having just a year left on his contract.
