I understand where your coming from but you’re argument seems very narrow, at least when it comes to the PL. Back in the 90’s Tottenham usually finished 10th or lower and at the start of the century we had the Sky 4, 4 clubs that always finished in the top 4 and where treated like the only 4 that mattered. While it’s taken many years of careful management Tottenham are now part of that big six, and they’ve sold many of their best players over the years and still continued to improve. So it’s absolutely possible for teams to grow over time. The biggest problem are the state backed clubs who come in and give the clubs unlimited funds to compete, which of course is completely unfair. While the authorities have moved far too slowly and have damaged the game over the last 20 years there have been some improvements and supposedly now there is protection in place.
Didn’t realise that the length wasn’t always 3 matches
