It's possible that Bournemouth will win Chelsea because of their consistency in their previous matches. Chelsea's performance is not stable and unpredictable which makes it impossible for you to rely on them. Bournemouth is in their best form and shouldn't be underestimated because they don't have a big name. Chelsea needs to improve their performance if they don't want to be bonus point for Bournemouth.
Chelsea are experiencing a decline in performance lately, where in the previous 4 matches they have not won even once, so it is clear that the match when hosting Bournemouth later will not be an easy match for them and also considering Bournemouth are in a positive phase this season so I think even though Chelsea chances of winning are higher, it does not rule out the possibility of losing again.
Thus the safest bet in their match is BTTS.
Actually, Bournemouth and Chelsea's performances are almost balanced so I think maybe they will get a draw but this match will be held at Chelsea's home ground so I think Chelsea will play as hard as possible in front of their supporters, if I myself am still quite sure Chelsea can still perform well in the EPL their poor performances lately will be used as evaluation material by the coach I predict Chelsea's victory and the worst result is a draw.
Chelsea's strength compared to Bournemouth is indeed not much different but I see Chelsea still slightly superior compared to Bournemouth. but yes in the match later Chelsea is indeed more favored and advantaged because Chelsea is the host, they will definitely get full support from their supporters so it seems that I personally also predict that Chelsea will win the match later. but if you look at H2H Chelsea is superior because they can win 4 times and draw 1 time.
I personally also believe that even though Chelsea has not been good lately when playing, of course Enzo will make his bitter experience a valuable lesson and Enzo Maresca will definitely fix everything and I saw when playing against Morecambe in the FA Cup Chelsea appeared extraordinarily good and impressive so it is possible that Chelsea's confidence will be better when playing against Bournemouth. but if Chelsea loses, for example, it seems that Chelsea this season is not ready to be a title contender exactly as Enzo Maresca said.
