Well if you talk about fiorentina, of course they can be lazy to watch chelsea going away with the trophy but I don't think if real betis can let them go so easily. because their performance in this conference league shows that they are determined to fight for this title till the end. However, I could remember when chelsea was still doing absolutely well of course this teams can never be a threat to them, but is obvious that thier performance is a little bit fluctuating. This is why I'm still having a doubt about them winning the conference league title.
Chelsea looks weaker now. You see Fiorentina and Real Betis they should not be underestimated against Chelsea. However, it is more clearer that Chelsea will win against any of the mentioned team because this is the only competition they are playing in, and the only trophy they might be able to get their hands on this season. Apart from fighting for a place in the UCL next season they need one trophy just like every other big team across other competition.
Although this cup may seem unimportant to Chelsea, I think it will have an important place as a cup they will win in Europe. That's why they care about this tournament like the Premier League. They have already played most of the matches and they have a few matches left to play in the Conference League. In my opinion, they are qualified enough to win the championship and are the biggest candidates to win the championship. I think Chelsea will win the cup.
