Actually we also can't claim that under Arne Slot they won't experience a decline, because they are not at the end of the season and now they are not even halfway through their journey this season, so we can't rush to judge.
I don't mean to underestimate Arne Slot, because after all now it can't be denied that he gave something good to Liverpool. Well, his next job is to maintain what he has created so far, don't let him decline at the end of the season. Because that's not easy to do, especially if they have problems, such as a storm of injuries and so on.
I would say they may, but its also not reasonable to bet according to how the yare going to have a decline. That would entail we would have to bet on them to lose games, and at the moment it looks like they are going to win. This is why I always suggest betting on them to win, in a martingale way, that works in sports much better than everything else. In dice for example, if you do martingale, even with 50% win chance, there is no way that you can go on for too long, because you could lose 10+ times in a row, and bankrupt your whole capital. That is why it only works at football, it's rare that any team would go like City, be great but then be terrible, any great team usually ends up having few bad games, but then recover.
So if you bet on Liverpool to win, every time, and anytime they lose, just bet bigger and bigger, eventually they will win, they won't go 10+ games without a win, hell even City didn't go 10+ games without a win, on their worst ever period.
