While Chelsea's current form might not be on par with Arsenal's, they're undeniably a formidable team. When they face their rivals, their determination multiplies. Admittedly, Arsenal holds the upper hand in terms of spirit and strength. Chelsea's only advantage lies in playing on their home turf.
Because Chelsea's advantage only lies in playing at home, this will still make it difficult for Chelsea to win because their opponents are much better than them in strength. Arsenal is very determined to win the match at Chelsea's home because Arsenal is very close to the top of the standings so Arsenal's enthusiasm will probably be very passionate at Chelsea's home because Arsenal really wants to win with a lot of scores in this match.
