For this season we do not know what the fate of the three teams that were promoted to the Premier League will be because the quality of the teams competing in the Premier League is very strong so that the promoted team must be able to maintain their good performance as they have done in the Championship.
I think the main target of the promoted team is to be able to survive in the Premier League because like Sunderland they have to work for a long time to be able to return to the Premier League so they must make the most of this opportunity.
Likewise with the teams that are already in the Premier League such as teams that are performing poorly like Tottenham and Manchester United of course they must be able to improve in the transfer market to be able to increase their strength because without any changes I think these two teams will find it difficult to compete with other teams.
Lower division is a combination of teams that were demoted from the main league which is the Premier League and teams from a division lower than Championship division, I don’t get faze when teams qualify from there, most often the ones that get promoted to Premier League don't last a season and when they do, after one more season, they lose steam and goes back to where they came from, it’s very likely that they wouldn’t last long here like we had last 2 seasons.
IPswitch town came in with 2 other teams last two season, the other team Luton town and Burnley were demoted and the following season, they are going back there with Leicester City after losing there spot too. One funny thing is Burnley and shuffle United that were sent away to championship are coming back to Premier League next season, some recycled teams are just playing around the European leagues trying to win something for theirself.
