I think you should not be sure about Chelsea winning the game against Fulham because they are not in the form and their team obviously is under pressure.
Yeah truly considering there performance this season the team is seriously under pressure the Chelsea team seriously need to sit down and evaluate there performance lately to figure out what that needs to be done for the team to regain it formal form because for now nothing is sure for Chelsea, even some small clubs Chelsea has a big chances of wining but they cannot so even wining Brighton this week doesn't determine there chances of wining Fulham on there next match on less improve there performance but although Fulham also is not much in a good form considering there other matches so the two clubs are just on the same form which will make there match against Chelsea very tough.
Because this match is played at Fulham's home ground, I think they will be slightly favored because Chelsea are also currently in very poor form and this is a West London derby match which of course will be very fierce for both teams.
I will favor Fulham in this match and I will look at the best odds to bet on Fulham winning.
What is happening to Chelsea right now is quite confusing because if we look at their squad, they are quite capable, but this seems to be due to internal team factors, perhaps because there are new players in the Chelsea squad now and they need more time to create a combination for their players and also a trainer so that he can unite Chemistry.
