Yeah as I said before Chelsea and Arsenal are on fire and in high confidence which means both teams can do anything unexpected, I won't say Arsenal can win easily because they defeated Manchester City in the last match because each match has a different moment. Chelsea who began to rise from bad results wanted to continue their wins record moreover it is a home match so the chance is 50:50 imo,
Some of Chelsea's players had a great International break, for instance Mudryk who scored a spectacular goal for Ukraine should be available for the game. Reece James will also return and start that game, so there will be a lot of hop that Chelsea will be able to do well. If Chelsea are able to beat Arsenal, they still have a lot of tough games ahead that if they do not try to get a good result from will find themselves at the bottom of the table, so it is an important period for them from now to the end of the year before teams have the opportunity for reinforcement.
