Fulham achievement so far is not really bad although they had lose several times from big teams but compare to other promotion teams Fulham had better position than them and Chelsea had serious internal issue after Tuchel sacked so they have to get new manager immediately and for this match Chelsea have to be careful playing against Fulham on their home ground because Fulham always be playing good as a host even 2 wins so far they get in home so this match won't be easy for Chelsea
Yes, despite this reason, Chelsea still have a big chance to win the next match
Although fulham appear tough when playing at home but Chelsea will benefit more because they have a history of winning 1-0 from fulham at Craven Cottage last season. Indirectly the confidence of the Chelsea players will not decrease.
And recently Chelsea managed to bring in former Barcelona striker, Aubameyang. He will add strength to Chelsea's forward line, and perhaps the upcoming match against Fulham will be his first Premier League match since Aubameyang's arrival some time ago.
