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.
You really can't tell for sure remember? though is obvious that chelsea will struggle so hard to win the title. Because that's the only hope they have this season, while other teams will be struggling as well. of course every team will be struggling to achieve something this season, Which is why the possibility for chelsea to win the title is not certain. You should know that real betis and fiorentina don't have any other hope apart from this conference league. this is why they are going to make it very tough, though among this teams that are competing for the conference league title I think chelsea is More likely to win the title.
