Indeed, sometimes in big matches like this Chelsea can play completely and they certainly don't want Arsenal to win easily at home. In history, these two teams have always had heated matches, but now we can see that the performance of the two teams is quite different. At least Chelsea must try everything to stop Arsenal and if they succeed, of course this will be more motivation for Chelsea to improve their performance so far.
Arsenal also won't be silent, however, they don't want Spurs or Manchester City to be so free next week and they have to win if they want to maintain stability in the standings. Mikel Arteta has his best squad for this season and their readiness to challenge for the EPL title again is also increasingly mature.
The very different performances of the two teams put pressure on Chelsea when they host Arsenal at Stamford Bridge. Chelsea, who have not yet found their best form, will have difficulty keeping up with Arsenal, who has appeared consistent this season. I have doubts that Chelsea will be able to hold back Arsenal progress even though they are playing at home. Arsenal are increasingly looking fierce this season and it is very difficult to stop them. Manchester City also became a victim of Arsenal ferocity in their last match in the EPL.
Arsenal who are keeping their distance from Tottenham and want to stay away from Manchester City, will certainly be very motivated to grab the three points at Chelsea headquarters. After successfully forming a very solid squad, Arteta will not let his team lose points in every match.
