Newcastle is an example and we can see them last season and the financial capabilities they have made Newcastle manage to maintain at least the top five positions until the end of the season and that is influenced by the good squad owned by Newcastle itself.
They don't spend a lot of star players, but they have pretty good performances. Indeed, since the change of owners, Newcastle has become better, they have been shopping for players but not too big like Man United, Chelsea or other clubs. Although at first I thought they would bring in a lot of star players, but that didn't happen.
If it compares to Notthingham it might be different, I think Newcatle is more experienced. Nottingham may struggle next season, this is because many players will be leaving. As always, those who get offers from big clubs will tend to leave because of more salaries and bigger teams.
