Crystal Palace is indeed improving; they even have a very strong mentality when they reach finals, destroying the dreams of strong teams. They previously defeated Manchester City in the FA Cup final and now they've destroyed Liverpool in the final and won the title. However, I still doubt Crystal Palace's ability to compete in the Premier League. I'm not even sure they can compete in the top four, even though they've improved.
The Premier League is very different from other competitions; every team needs consistency, and Crystal Palace can't be consistent in every game. Crystal Palace will remain focused on other domestic competitions next season rather than the Premier League. Liverpool have a lot of work to do in this match, with Arne Slott having to complete several tasks, and several incoming players haven't fully integrated into the team. This must be fixed immediately by Arne Slot so that next season he can defend the EPL title.
Crystal Palace is improving, and I agree with you, winning two titles against top Premier League teams does not guarantee that they will be able to compete in the Premier League next season. They defeated Manchester City in the FA Cup final, and we all knew how badly Manchester City were last season, so any team could beat them. I was not surprised when Crystal Palace defeated Liverpool in the final because Liverpool has usually struggled against them.
Liverpool only beat them one time last season, and it was a narrow win, so I was not surprised by the defeat. Crystal Palace, on the other hand, will not be strong enough to compete for the league title next season, no matter how well they play. Crystal Palace will struggle to finish in the top four next season, but they could finish in a good position because they will also compete in the Conference League.
