The Premier League is always fiercely competitive, with several teams competing quite closely. Although Chelsea has shown good performance, I don't think it will be easy for Chelsea to win the Premier League title next season, even though they are the favorites.
Their achievement in the Club World Cup is certainly quite positive, especially for the mentality and confidence of the Chelsea players heading into next season.
Chelsea is able to play a combination of midfielders and forwards that are in sync well enough to confuse opponents. Therefore, Chelsea should be considered a dangerous team next season, because Premier League teams that can't read Chelsea's tactics will be more easily defeated by Chelsea. So, it's not just about winning the Premier League next season, but also about who Chelsea can outwit when they meet in a match. And we saw and experienced the same thing with PSG in this Club World Cup final.
