Chelsea aren't in good condition, they're keep draw for the past 2 matches and lose, I don't think Chelsea will beat Arsenal even though the match will happen on Chelsea's home.
it is not impossible that Chelsea can hold Arsenal. even Southampton can also hold Arsenal to a draw.
I think the odds of this match are 50:50. Chelsea may have had some bad results in their last game. but Chelsea won't lose easily at home. I think a draw is quite possible in this match. or a small win by 1 goal for one of the teams. but in terms of the game, I believe Arsenal can dominate more.
Chelsea so far already meets 2 big teams this season Manchester United and Tottenham although they cannot able to gets wins from these teams but at least Chelsea didn't lose and according to meetings statistics between them indeed Arsenal records is more good than them because Chelsea only can able to gets 2 wins from 5 matches but if we see Chelsea home matches records this season i think Chelsea is quite impressive so i am quite optimistic Chelsea can playing well this time and bounce back while against Arsenal but in my opinion draw is fair result for both of teams however Chelsea indeed faced tight schedule this weekend because after against Arsenal this sunday they will fight against Manchester City at Carabao Cup
