I agree with what you said Fulham has a chance to win this match even though Chelsea are favored by the bookies but in my opinion the bookies only draw conclusions from past history or take them from Head To Head statistics so that the odds given by the bookmakers will be higher small for Chelsea but still we should not consider it a possibility that Chelsea has the right to win because we know how different Chelsea's performance is from Fulham at the moment and it is very different and superior to Fulham in terms of current performance.
I tried a little quick analysis of the results. I think there are 2 possibilities between Fulham winning or ending in a draw and for a score of 2-1 and this is just a quick speculation from the analysis I did.
Currently, almost the majority of people really hate Chelsea or no longer have confidence in this club. Before Chelsea starts to rise, it looks like it will continue to lose its fans and also its popularity will definitely decline unlike the last few seasons and this is Mauricio Pochettino's responsibility as a coach. immediately look for alternative ways to immediately improve the performance of the players to return to their glory days.
