The Premier League has seen as many monster sales as it has purchases over the last 28 years.
While England's top division is arguably the number one place for world-class stars to play, some of them just can't resist returning to the continent for clubs like Real Madrid or Barcelona.
The biggest Premier League sale in history involved the latter as Philippe Coutinho jumped ship from Liverpool, but the Reds haven't exactly missed him since receiving over £100 million.
Well, hold that thought, because the team at HITC Sport decided to work out every Premier League club's record sale on their YouTube channel and assess how every team replaced them.
For example, The Irish Guy looked into how Manchester United dealt with flogging Cristiano Ronaldo, how Chelsea coped with ditching Eden Hazard and, well, you get the picture.

You can check out the full video down below, but keep scrolling for our comprehensive breakdown to see how well your club dealt with its biggest ever departure.
Arsenal
Sold: Alex Oxlade Chamberlain to Liverpool
Replacement: Henrikh Mkhitaryan from Manchester United
Rating: 7/10
It's pretty surprising that Oxlade-Chamberlain is Arsenal's richest sale considering all their flogging over the last 10 years and we'll let it slide that Mkhitaryan was effectively replacing Alexis Sanchez.
But we think 7/10 is pretty generous for Mkhitaryan when he proved, as he had already done at Old Trafford, that he isn't really cut out for the Premier League with just nine goals in 58 games.
Aston Villa
Sold: Christian Beneke to Liverpool
Replacement: Rudy Gestede from Blackburn Rovers
Rating: 4/10
Replacing the then prolific Benteke was never going to be easy and Gestede's five goals in a season where Villa finished rock bottom of the Premier League suggests 4/10 is rather kind.
Bournemouth
Sold: Tyrone Mings to Aston Villa
Replacement: Lloyd Kelly from Bristol City
Rating: 2/10
While Mings has gone on to thrust himself into England contention at Villa Park, Bournemouth have sunk into a relegation battle where their young replacement has made just one League Cup appearance.
Brighton & Hove Albion
Sold: Leonardo Ulloa to Leicester City
Replacement: Darren Bent from Aston Villa
Rating: 2/10
Bent was already past his best by the time he appeared at the Amex Stadium and it's no coincidence that the Seagulls slumped down the Championship for failing to replace their main source of goals.
Burnley
Sold: Michael Keane to Everton
Replacement: Ben Gibson from Middlesbrough
Rating: 1/10
Bagging £30 million for Keane was a great coup at Burnley and while, yes, Gibson has hardly been a suitable replacement, Sean Dyche has barely missed his record departure and sits just two points behind him in the table.
Chelsea
Sold: Eden Hazard to Real Madrid
Replacement: Christian Pulisic from Borussia Dortmund
Rating: 5/10
Seriously, could anybody have truly replaced Hazard at Stamford Bridge?
The jury is still out on Pulisic, but the American has done a pretty decent job so far with six goals in 28 outings. He just never looks like becoming a player of Hazard's calibre even when he reaches his peak.
Crystal Palace
Sold: Aaron Wan-Bissaka to Manchester United
Replacement: Martin Kelly from... Crystal Palace
Rating: 4/10
Yeh, Roy Hodgson didn't really get the chance to plug the gap left by Wan-Bissaka last summer and has instead deployed former Liverpool man Kelly at right-back with mixed results. 4/10 seems about right.
Everton
Sold: Romelu Lukaku to Manchester United
Replacement: Wayne Rooney from Manchester United
Rating: 6/10
If it wasn't for Sam Allardyce's arrival completely curtailing Rooney's return to Everton, he might have scored more than the 11 goals he did and stuck around for a few more seasons.
And although he was a sound enough replacement for Lukaku, he couldn't provide the same sort of goals and the Toffees are still on the search for their next number nine three years later.
Leicester City
Sold: Riyad Mahrez to Manchester City
Replacement: James Maddison from Norwich City
Rating: 8/10
Inspired. The sale of Mahrez could have been a complete disaster for the Foxes, but poaching Maddison from the Championship has helped thrust them into the Champions League places this season.
Liverpool
Sold: Philippe Coutinho to Barcelona
Replacement: Naby Keita from RB Leipzig
Rating: 7/10
Ok, yes, Keita isn't really a direct replacement - don't blame us - but Liverpool have adjusted their style of play as opposed to looking for a new number ten to fill Coutinho's boots.
The Reds are worthy of more praise for spending the Coutinho money on Virgil van Dijk and Alisson Becker in order to claim the Champions League title and their maiden Premier League crown.
Manchester City
Sold: Kelechi Iheanacho to Leicester City
Replacement: Gabriel Jesus from Palmeiras
Rating: 9/10
It's pretty mental that Iheanacho is the player that has earned City the most dosh.
And while it's somewhat cheating by calling Jesus, who had already arrived at the club, his replacement, there can be no doubting that he's completely outshone his Nigerian predecessor.
Manchester United
Sold: Cristiano Ronaldo to Real Madrid
Replacement: Antonio Valencia from Wigan Athletic
Rating: 7/10
The fact The Irish Guy didn't select Gabriel Obertan means United have dodged a bullet here.
We can let 7/10 pass considering Valencia went on to captain the Red Devils and make over 300 appearances, but let's not pretend as though he vaguely held a candle to Ronaldo.
Newcastle United
Sold: Andy Carroll to Liverpool
Replacement: Demba Ba from West Ham United
Rating: 9/10
The Toon hardly missed Carroll when they romped into the next season with a fifth-place finish, following it up a Europa League quarter-final the following year, across all of which Ba scored a cool 29 goals.
Norwich City
Sold: James Maddison to Leicester City
Replacement: Todd Cantwell from... Norwich City
Rating: 9/10
One of the few instances where a club turned to their academy after getting the big bucks. Cantwell has more than lived up to expectations and will likely remain in the Premier League regardless of whether the Canaries are relegated.
Sheffield United
Sold: David Brooks to Bournemouth
Replacement: Ravel Morrison from Ostersund
Rating: 1/10
In truth, the Blades haven't really replaced Brooks at all - have they even needed to? - but 1/10 is bang on the money if we're counting Morrison, who has been dumped on loan at Middlesbrough, as the closest candidate.
Southampton
Sold: Virgil van Dijk to Liverpool
Replacement: Jannik Vestergaard from Borussia Monchengladbach
Rating: 6/10
The Saints were never going to stumble across a defender as good as Van Dijk again, so giving them a 6/10 for finding a centre-back who is arguably out of their league to replace him is well deserved.
Tottenham Hotspur
Sold: Gareth Bale to Real Madrid
Replacement: Erik Lamela from AS Roma
Rating: 3/10
It's well documented how Andre Villas-Boas misspent the Bale money during the summer of 2014.
And while signing a player once considered the 'New Messi' seemed like a justified decision, it's remarkable that Lamela is still in north London despite scoring just 33 goals in 207 matches.
Watford
Sold: Richarlison to Everton
Replacement: Gerard Deulofeu from Barcelona
Rating: 8/10
Look, we're going to say it: Richarlison's spell at Watford was overrated.
Admittedly, the Brazilian has gone on to shine at Everton, but Deulofeu has done no more or less than what his predecessor was achieving at Vicarage Road before him.
West Ham United
Sold: Dimitri Payet to Marseille
Replacement: Robert Snodgrass from Hull City
Rating: 3/10
Cruel. A 3/10 is rather harsh considering Snodgrass has been West Ham's shining light this season with five goals from midfield, despite the fact, yes, the Scot isn't anywhere near the quality of Payet.
Wolverhampton Wanderers
Sold: Helder Costa to Leeds United
Replacement: Patrick Cutrone from AC Milan
Rating: 4/10
This will only be confirmed when Costa makes his move to Leeds United permanent but if we're letting this technicality slide, then 4/10 is just about the most Cutrone deserves for his doomed spell at Molineux.
Liverpool spent the Coutinho money well
So, there you have it, Premier League clubs don't always spend the big bucks wisely.
Maddison is the best replacement of the lot for our money, as well as one of the most financially shrewd, although Newcastle signing Ba and Norwich promoting Cantwell are also very impressive.
But if we forget the rules for a second, then Liverpool are perhaps the most applause-worthy.
Keita might not have set the world alight on Merseyside, but flogging Coutinho in return for Van Dijk and Alisson has made Liverpool the unstoppable force they are today.
It goes to show that selling your star man can make you into a star team.
