I don't wanna expect big from promoted teams. I don't wanna see the same result happened to the Leicester, Ipswich, and Soton to happen with Sunderland, leeds, and Burnley. However, seeing how newly promoted teams performs in Championship. I skeptical about those newly promoted team will able to survive.
Sheffield and Burnley looked good in Championship, but not really sure if they can stay survive. I admit how the gap between the existing team in PL is far compared to the newly promoted teams. It creates the big difference that's hard to catch up by newly promoted team
Difference of quality is widening after every season because Championship sides are not able to invest like Premier League teams are doing in last few years which is giving them good advantage in this season relegated team Leicester City is having 25 points while Tottenham which is ended at 17th have 38. Next season is going to be more challenging with Leeds United, Burnley and Sunderland surely try their best for staying here and this will increase challenges for few teams which were not able to perform as they needed in last season but still these could be faced the toughest situations.
Now it's never been easy for teams to be stayed for long time in Premier League after having promotion because it needs good strategy with good funds which helps them for having good players into their squads game is almost change consistency and quality needs money.
That's true the level of competition in the championship compared to the premier League is widing an this is the reason why most teams that come to the premier League from the championship is going back like Leicester City, the problem has been investment when a team is only focusing on selling the players that are doing well without giving attention to the growth of the team that team is definitely going to suffer next season I expect that the teams coming to the premier League should do well to invest in their teams and bring a little bit of quality to the premier League
