Over the past two years, all six clubs that have been promoted to the Premier League have been relegated again at the first time of asking.
That marks a concerning trend in English football as the other 17 clubs in the top flight have essentially had an uninterrupted stint of a bare minimum of three years amongst the elite - meaning whichever sides come up each year are at a growing disadvantage both on the pitch and financially.
Leeds, Burnley and Sunderland will aim to put an end to the growing monopoly between the Premier League and Championship.
Here, Flashscore takes a look at how each club is shaping up heading into the new season.
Leeds adding physicality
Leeds won the Championship on goal difference last season, amassing 100 points alongside Burnley to achieve automatic promotion.
Daniel Farke's side learned their fate back in April, so they have had plenty of time to prepare for a mammoth challenge in the Premier League.
One of Leeds' key issues last season was their goalkeeper, with Illan Meslier making plenty of basic errors.
The Frenchman was bailed out on several occasions by his teammates at the other end of the pitch - but that wouldn't have been as simple in the much harder Premier League.
Leeds have addressed that issue over the summer by signing Lyon goalkeeper Luacs Perri in the hopes of giving them a more reliable defensive foundation.
Another problem Leeds have faced in past top-flight campaigns has been a lack of size and physicality in their squad, something that has also been addressed over the summer.
Of their seven new signings, six are over six-feet tall: Perri (6'5"), Anton Stach (6'4"), Sebastiaan Bornauw (6'3"), Jaka Bijol (6'2"), Sean Longstaff (6'1") and Lukas Nmecha (6'1"), while Gabriel Gudmundsson comes in at 5'10".
That gives them a much greater chance of dealing with the physicality in the Premier League.
Half the battle for newly promoted clubs is being able to compete with the sheer athleticism that top-flight players possess while also maintaining incredible footballing ability - something that Leeds have appeared to try and address in their summer business.
In terms of what they need next, Farke has been clear that he wants attacking reinforcements.
"We won't panic. It's not necessary to bring a traditional number 10 if he doesn't have the quality," Farke said.
"But this type of player, same as the striker position and winger position, in the offence we need good additions in all positions in order to be competitive in the best league in the world."
Several names have been linked, including Fulham striker Rodrigo Muniz and Leicester forward Bilal El Khannouss, although there have been no concrete reports of any movement in recent weeks.
Leeds certainly need more firepower if they are to compete, but with a few weeks left in the window, that is something that can still be addressed.
Burnley leaning on experience
Burnley also stormed to promotion last season and have had a long time to plan for Premier League football - but have perhaps faced more pitfalls than their fellow newcomers.
The Clarets boasted a record-breaking defence in the Championship that managed 30 clean sheets and conceded just 16 goals.
That defensive unit has been torn apart over the summer, with CJ Egan-Riley departing for Marseille on a free transfer and goalkeeper James Trafford returning to Manchester City.
Scott Parker's side have also lost their captain and top scorer, Josh Brownhill, after failing to tie him down to a new contract.
That has resulted in plenty of change at Turf Moor over the summer. However, something Burnley have done well is offset those losses with the signing of experienced players, in addition to re-signing their loan stars from the previous campaign.
Jaidon Anthony, Marcus Edwards, Zian Flemming and Bashir Humphreys have all signed permanently, while the defence has been bolstered with the arrivals of Kyle Walker, Axel Tuanzebe, Martin Dubravka and Quilindschy Hartman.
Some Premier League know-how has been added further up the pitch as well, following the signings of former player Jacob Bruun Larsen and Chelsea duo Lesley Ugochukwu and Armando Broja. Meanwhile, the Clarets have also brought in exciting young talents like winger Loum Tchaouna and goalkeeper Max Weiss.
The fact that plenty of Premier League experience has been brought in can only be a positive and represents a good strategy for attempting to stay in the top flight.
"I'm really pleased that we've added some extra quality to us. Certainly, some experience as well," Parker said.
"It's three (Broja, Ugochukwu and Dubravka) players who have been in and around the Premier League and tasted it and probably know what to expect in the division."
One major worry would be Burnley's lack of an attacking threat, as it remains to be seen whether or not Broja can score enough goals to give a realistic shot at survival - something they may address in the closing weeks of the transfer window.
Sunderland attempt to bridge the gap
Unlike Leeds and Burnley, Sunderland have had around a month less to prepare for the Premier League after winning the playoffs at the end of May.
The Black Cats also have an arguably bigger gap to close after finishing 24 points away from the top two, although that doesn't mean they'll start the new campaign 24 points behind - it's a fresh slate for everyone.
Sunderland's biggest task was undoubtedly trying to bridge the gap in quality between their squad and even the 'worst' sides in the Premier League.
Both Leeds and Burnley have the benefit of having played in the top division in recent seasons and thus have squads of players with at least some top-flight quality to build from.
The same can't be said for the Wearsiders, who were last in the Premier League eight years ago and have since gone through a plethora of players and managers.
Sunderland have tried to do that admirably, making 11 signings at the time of writing for a reported initial spend of £132 million.
Those additions feature players experienced in either the Premier League or top divisions of Europe, including Arthur Masuaku, Reinildo Mandava, Simon Adringa and Granit Xhaka.
Couple that with exciting incoming young talents like club-record signing Habib Diarra, Noah Sadiki, Chemsdine Talbi, Robin Roefs and Marc Guiu, and the Black Cats have built an exciting yet unpredictable squad to battle for survival.
Those young additions keep with the nature of Sunderland's business over the last few years in only paying fees for players aged 24 or under, but the hierarchy has shown flexibility this time around, something that was a frequent criticism when the club were still in the Championship.
Enzo Le Fee (aged 25) and Omar Alderete (28) both arrived for modest fees alongside Xhaka (32) in what represents a slight tweak in approach from the Black Cats' ownership.
While more defensive reinforcements are needed - and possibly another forward - no one can say Sunderland haven't 'given it a go' in an attempt to bridge the growing gap between Premier League and Championship, regardless of what their fate may be in nine months.
