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
The balance hasn't been created completely since Chelsea were managed by a new coach, that's what I saw from their defeat to Brighton. We can't beat Chelsea's recent results. because in the previous match they worked very well before finally they had to accept defeat. Arsenal are of course a very strong opponent, they don't need to target a win because a draw alone is enough for them.
