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.
Just because Crystal Palace can win against Liverpool does not mean that they are improving. They always have the habit of starting well and ending badly. To prove me wrong when the season starts fully, then you will see what they are made of. As for Manchester City, we are going to do something different, and there are other big guns, so it's going to be very hard for Crystal Palace to win even the Premier League; they don't have the strength to pull that off.
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.
All competition needs consistency because without consistency, there is no trophy, and the likes of Crystal Palace and Tottenham don't show consistency at all, they are always starting well, but at the end of the season, it always ends in disappointment. And the advice of focusing on domestic leagues will help them because they don't have the squad to win the Premier League. So they should focus, and if they want to improve, then they need to start doing better than what they are doing now.
