It doesn't seem to be something strange anymore when the promotion team can't play well, and or can't get good results in the Premier League. Because anyway, cases like this also at least happen almost in all major leagues in Europe so yes, I think it remains a natural result when the promotion team cannot play well here. But even so, at least with the promotion team can stay in the Premier League longer or not quickly relegated back. Then of course, with them being able to last longer here of course it has been a big achievement for them.
Haha, they hope this promotion team can be like Leicester City who made history come as a beginner and leave as a champion obviously this is a rare moment even in the next 10-20 years there won't necessarily be a promotional team that will be able to do it. As you said staying in the Premier League in the next season is a great achievement then in the 2nd season they were able to attract the attention of sponsors sufficient funding can increase the strength of the team by bringing in new players or take advantage of academy players like Fulham did, Fulham comes to the Premier League in the 2022/2023 season so far they are still in the middle of the standings.
when the promoted team does not have the financial strength to prepare to compete with other strong teams in the Premier League, of course, the promoted team will experience difficulties.
If they have strong enough funds, they can buy new players to strengthen the team so they can at least survive their first season of promotion. In season two they should do it better.
but if the promoted team does not have good finances, with as few players as they are it will be challenging to compete with rich teams and more players with good quality players.
