Fulham is much better than Chelsea this season and also in terms of points scored although the two are not much different but I think Fulham will be the favorite in this match and it will be a golden opportunity for Fulham to beat Chelsea at home.
Even so I hope you don't bet too much on Fulham winning because this match is difficult for us to predict even though Chelsea is experiencing bad conditions, but I think Chelsea will try their best in this match.
Not only this season, even since last season Fulham has always been better than Chelsea and it looks like this time we will see Fulham again being able to beat Chelsea at home. If we look at the meeting between the two last season, Fulham was able to beat Chelsea at home with a score of 2-1 and I think this time Fulham can do it again with a better score of 2-0 or 3-1 considering that Chelsea is very far from being productive. Another fact about Chelsea is that in September they have not recorded a single goal in the EPL competition so we can see that they will again have difficulty winning in the next match against Fulham. So, it is fitting that Fulham will win very convincingly and I still doubt Chelsea if they continue like this in the future.
Although I agree that Chelsea's recent performance, particularly their goalless streak in September, is concerning, have we forgotten their victory over Brighton? Yes, Fulham defeated Chelsea at home in the previous season, and your guess of a 2-0 or 3-1 victory might come to pass. But Chelsea's willingness to turn things around shouldnt be underestimated, in my opinion. Although I share your concerns with Chelsea's performance both now and in the future, isn't football about surprises and hope?
