We have been told for years that the financial 'bubble will burst' in the Premier League, but it never has.
Indeed, any time the television revenues go up, transfer fees also shoot up.
With Manchester City poised to smash their transfer record to land Jack Grealish and Chelsea bidding megabucks for Romelu Lukaku, Planet Sport looks at just how well Premier League club's record signings have fared.
Arsenal - Nicolas Pepe - £72million
It's fair to say that this one hasn't worked out. Well, it hasn't yet at least.
Pepe has been okay in fairness, but he just hasn't justified the size of the fee. Last year it was even reported that Arsenal were conducting an internal inquiry as to how they were persuaded to agree the deal.
Still, even though they definitely overpaid, at least they got a good player out of it.
Aston Villa - Ollie Watkins - £28million
There is absolutely no doubt about this one: Aston Villa hit a real home run with Watkins.
It didn't always look an entirely safe bet, though. Watkins was untested in the Premier League, although he had just hit 26 goals in 50 games in the previous campaign for Brentford in the Championship.
Last season Watkins scored 14 Premier League goals, was capped by England, and scored at international level, so £28million suddenly looks pretty good value.
(Note: Emiliano Buendía is Aston Villa's new record signing, but at the time of writing has yet to play a match for them.)
Brentford - Ivan Toney - £10million
Toney was the man who Brentford turned to when they needed to replace Watkins, and it definitely looks like they got value there.
Indeed, Toney outscored Watkins in the Championship, hitting 33 goals in all competitions including 31 in the league.
The ultimate litmus test of this signing will be what Toney can do in the Premier League, but for the money they paid for him, Brentford have already had incredible value out of Toney.
Brighton - Adam Webster - £20million
Webster is one of those players who don't sound very exciting, but he rarely lets anyone down.
The centre-back has worked his way up to the Premier League, where he has become a crucial part of the Brighton spine.
There is little to really say about Webster, and that is testament to the quiet authority he has brought to the Brighton defence.
Burnley - Ben Gibson - £15million
There is no way to sugarcoat it: Ben Gibson was a disastrous sighing for Burnley.
The Clarets barely got any games out of Gibson before packing him off back to the Championship with Norwich.
Burnley don't spend big money often, so it will have hurt them to have got this one so wrong.
Chelsea - Kai Havertz - £75.8million
That said, the early signs are encouraging, aren't they? The German scored a Champions League final-winning goal to cap his first campaign in England, which is about as good as it gets.
There is surely a lot more to come from Havertz too, but you spend that kind of money to win the biggest titles, and he has already delivered one.
Crystal Palace - Christian Benteke - £27million
On paper, this looked a really good signing for Palace. Benteke was leaving Liverpool after a frustrating spell for the Reds, but the Aston Villa form that earned him that move to Anfield was still fresh.
It started out well too, with the Belgian hitting 15 Premier League goals in his first season at Selhurst Park.
The following four years yielded just 16 more, though. It was enough to get him a new deal, but it's hard to say he has delivered on record-signing level expectations.
Everton - Gylfi Sigurdsson - £45million
On the pitch, you'd have to say that Sigurdsson has probably just about justified his transfer fee, but only just.
The Icelandic midfielder has not been a standout performer, but he has been a consistent one over a sustained period of time.
You get the feeling he won't be Everton's record signing for long, and his time at Goodison Park looks to be coming to an end too.
Leeds - Rodrigo - £27million
There is no question that Leeds are building something very impressive right now, and that means they may have already outgrown record-signing Rodrigo.
He arrived in England without much of a pre-season and struggled with injuries as a result, but his end-product wasn't anywhere near what had been expected.
There have been reports he is unsettled and wants to return to Spain, and you sense Leeds would not stand in his way.
Leicester - Youri Tielemans - £40million
The Foxes are where they are right now because they recruit brilliantly, and Tielemans is a perfect example of that.
The Belgian is young, he's quality, still has untapped potential and yet is contributing right now as well.
In addition to his fine performances in the Premier League, Tielemans scored the winning goal in the FA Cup final as Leicester beat Chelsea at Wembley.
Liverpool - Virgil van Dijk - £75million
That has almost been forgotten, because if you had to choose one player who turned Liverpool from a top team to a Premier League-winning team, it was the Dutchman.
The fact he missed a large chunk of last season and Liverpool struggled so much without him just highlighted further what a superb signing he has been.
Manchester City - Ruben Dias - £64.3m
Although the Citizens have spent big fees regularly in recent times, it's actually quite hard to remember any real flops.
Dias certainly isn't one of them. The centre-back won the Football Writers Play of the Year award last season, and he absolutely deserved it.
Manchester United - Paul Pogba - £89.3million
Where on earth do you start with Paul Pogba? He has to be the most enigmatic player we have seen in recent years.
Pogba probably is a £90million quality asset in the modern market, although his commercial value is included in that. He hasn't justified the fee on the pitch though.
Add into the fact that Man Utd even had to buy him back after initially losing him for nothing, and you'd struggle to argue that Pogba has been anything more than a moderate success at Old Trafford.
Newcastle - Joelinton - £40million
Mike Ashley is a well-known skinflint, but when he does release the purse strings a little and then it's spent on Joelinton, it becomes easier to understand why he doesn't do it more often.
Joelinton has simply not delivered for Newcastle and it's far from a secret.
The Brazilian has contributed just six Premier League goals in 69 matches, so he can't even say he hasn't had a fair crack of the whip.
Norwich - Steven Naismith - £8.5m
Naismith was a fine fringe player for David Moyes' Everton, and many believed he would shine if given more opportunities.
Those opportunities were given to him by Norwich, when they made him their record signing in 2016.
However, injuries restricted him and he failed to deliver anything of note for the Canaries.
(Note: Milot Rashica is now Norwich's record signing but at the time of writing he has yet to play a game for the club.)
Southampton - Danny Ings - £20m
When Ings moved from Burnley to Liverpool, you feared he would be a small fish in a big Anfield pond. An anterior cruciate ligament injury early in his Liverpool career didn't help, but as expected Ings found opportunities limited.
He has rediscovered his best form at Southampton, though, where he has scored 41 goals in three seasons.
Ings has definitely delivered for the Saints, who may now have to fight off the attentions of Tottenham who reportedly see him as a potential replacement for Harry Kane.
Tottenham - Tanguy Ndombele - £53.7m
Spurs have slipped down the Premier League pecking order simply because they have had too many transfer failures, and Ndombele is definitely on that list.
Tottenham's transfer policy, which often restricts them to signing players with potential resale value, is highly conducive to risk, and Ndombele never looked a very safe bet.
He has not been a total flop, it should be stressed. The Frenchman has played over 75 times for the club, although he has never looked a £53million player.
Watford - Ismaila Sarr - £40m
Sarr looked like he could be a potential star in the Premier League when he first joined Watford, and he was quickly linked with an even bigger-money move away.
That looked even more likely after the Hornets were relegated, but they did brilliantly to hang onto him in the Championship.
It was a decision which paid dividends as they were immediately promoted back to the top flight, but a relegation on his CV has tainted Sarr's legacy at Watford a little. That said, a big Premier League season and his stock will quickly rise again.
West Ham - Sebastien Haller - £45m
If we are honest, signing players from the Eredivisie for huge money has rarely worked out well for Premier League clubs.
This one wasn't quite Alfonso Alves territory, but 10 goals in 48 Premier League appearances didn't exactly scream 'success' either.
Wolves - Fabio Silva - £35.6m
This one is a very tough one to judge. If we are honest, there was a strong 'rush it through before Brexit' feel to the signing, with Wolves knowing the youngster would be out of their reach once work permit rules came into effect for European players.
Fabio Silva is only 19 still, and he has four Premier League goals to his name despite his limited opportunities.
As or right now, though, you'd have to say he is not delivering the value you'd want for a record signing. However, he has time to change that.
