They have and the reason they did, was because of their expenditure. Granted to do what they did, they punched slightly higher than what was expected.
So when Leicester lose players it's because they are poached? Yet when other teams that you often mention sell players it's because of an entirely different reason. Apart from probably Man city currently, even the other teams in the big 6 get their players poached. When Real come calling and all that.
Big fish eat smaller fish. Apart from rare, occasional exceptions. The more money you have as a club, has a direct correlation with how well you do. It's not about recognising a footballer it's about how much you can pay for one. Leicester get their players poached and in turn poach players from less wealthy clubs.
When they won their trophies they did recognise what a footballer was. So by your own admission, when they got relegated they didn't. Change their team each season, but still have Jamie Vardy upfront since about nineteen eighty fucking four! Only a select few Premier League clubs can afford what he's currently on.
Everton spend far less and they don't get relegated. Can any team get relegated from the Premier League???? Of course they can, but will any of the big 6? Course they fucking won't!! Leicester when they got relegated, was as close as it's gonna get to any of those teams dropping. They didn't get it wrong, they failed fucking spectacularly on a level not seen before in recent times with their expenditure.
All those teams you mentioned have billionaire owners and consequently fish in bigger ponds, so catch bigger fish. Some teams are able to punch significantly higher for a period of time. Think for example Blackpool, Huddersfield, Barnsley, Wigan and Reading in the past and Luton currently. Recruitment staff and others get poached too, when they succeed. Only so many rabbits you get can get out of a hat as well.
Some clubs will exceed expectations of where they should be at different times. Likewise, other clubs will significantly underachieve for a period of time. Look at Sunderland, Derby, Bradford etc. Remember the world class players at Boro, Bolton and Portsmouth?? Even fucking Wednesday won a trophy, were finishing high in the league and playing in Europe. They haven't been in the Premier League this fucking century.
The more money you have the better footballers you get and the more successful the team is. Blackburn didn't win the title because they could recognise a footballer, they were able to buy the best players, because they had the most money. When that money was no longer available they dropped, the same as Wigan and Reading. Before Roman, Chelsea had absolutely appalling attendances and a million miles away from the traditional big 5. With more money than anyone else, they became for a period more successful than anyone else. However, currently they don't recognise a fucking footballer, have spent eye watering amounts and failed spectacularly.
The amount spent on wages, transfers and infrastructure, has a direct correlation on how well you do. Sometimes for a period clubs do better than they should and sometimes don't. Ultimately it's about how much money you have. Rotherham and Peterborough can't compete in the championship. Not because they can't recognise a footballer, but because they have no money and have the lowest wage bill in that league. The fact that both those clubs are able to get out of L1 on a regular basis, shows they can recognise a footballer. Both clubs don't have anywhere near the biggest resources in L1, but their resources are competitive and thus able to thrive and do well with, as you say, 'recognising a footballer'.
Do teams like Rotherham and Peterborough suddenly lose the ability once in the Championship to 'recognise a footballer?' They simply don't have the finances to compete. If any of the owners of Bournemouth, Brentford, Fulham and Brighton sold up and bought Rotherham. Then Rotherham would take their place as a permanent fixture in the Premier League.
Look at all those clubs you mention and their geographical location. Is that a coincidence? Of course it isn't, is it? The location consistently receives significantly more investment and is far wealthier. Which is why these clubs were able to attract billionaires. What about Newcastle and Man City you say ?? These are huge traditional clubs, with a little more investment can compete with and surpass the traditional big 5.
Those clubs you mention are on a totally different level. Why didn't those owners invest in similar size clubs in the north, such as, Rotherham, Huddersfield, Bradford, Hull, Carlisle???? Geographic location, investment and wealth. I'm sure York, has shops, restaurants and enough forward thinking people to be a palatable place for even for someone as discerning as yourself. However, as nice as York is,as a city, it isn't on the same playing field as the geographical location of all those clubs you mentioned. Neither does the football club have the stature of a Man City or Newcastle. So it is never going to have a billionaire owner take over.
Quite the fucking rant

I could have and should have just wrote, in the majority of cases and time wealth has a strong correlation with success. The wealthier an entity is, the more successful it will be.
Oh and btw, it didn't escape my attention that you failed to address your questionable use of vocabulary. By ignoring it completely, you've confirmed for me at least, that you knew exactly what you were doing when writing it.
Regarding your other post about Sheffield being pretty much a shit hole and having less forward thinking people than other areas. You claim that you weren't saying it has more problem sections of society, than other areas, just less forward thinking people. You come across as pretty binary, so who are these people that are neither problem sections of society or forward thinking people???
You appear to hate Sheffield with an absolute passion, to be honest it does worry me, what the root cause of this is. Like many places Sheffield has the good, the bad and the ugly. Lacks in some areas and over achieves in others. Sheffield University was voted the best University by students. So many students stay here after graduation, including international students.
I met, married and had children with my wife, living in China for many years. She fell in love with Sheffield and has lived here for 16 years now. Course she misses China and we go back regularly. She chose Sheffield over Beijing, Shanghai or any other places in China, because she loves the place. Many Chinese people do, because Sheffield has some great qualities as a City.
No I don't know any Chinese billionaires



I am actively looking though lol. And I do convert and spread the word of Sheffield United throughout the land. Plenty of Blades around
