Chelsea going head to head with the Gunners is going to be a cracker since nobody can really tell the score line. Chelsea are not doing that bad but against a side that's having this hunger to prove that they can be title contenders, and Chelsea continues with the way they played against Brighton, I doubt they can beat Arsenal with those ridiculous errors coming from the back line.
Also the defense of Chelsea isn't strong to hold the likes of Gabriel Jesus, Martinelli and Saka(that's if he'll start because of the little injury which he has recovered from). And the defense line of Chelsea is really missing players like Reece James and Chilwell..IMO, the percentage of getting a win for Chelsea is 45%.y
Chelsea will play at home and Arsenal have a poor record when they travel to Chelsea. but of course it can not be a reference because this season the two teams appear with different strengths.
Arsenal are much stronger and more consistent at the moment and that is in contrast to Chelsea who have not been able to be consistent until now, especially after they changed coaches a few weeks after the start of the season making their consistency even worse.
on paper in terms of quality Arsenal will be favorites in this match although anything is still possible but I don't think Chelsea will be able to win this game, win for Arsenal or will end in a draw, that's my prediction.
