At least, because previously Arsenal managed to beat Manchester City, of course, this factor will make it predicted that Arsenal will also win against Chelsea. After all, we are all aware that Chelsea's situation and conditions have been devastated since last season, and have not improved until now. Therefore, it is natural that Arsenal remains the team that is projected to win this match and as such, the home and away factor is no longer important at this moment because on paper Arsenal will definitely win.
I will be a little different from you. Indeed, on paper Arsenal will be favorites to win the London derby this time, especially as Arsenal have never lost in the EPL league so far. But if in football we don't have to be 100 percent sure that Arsenal will win this derby, we have to leave a little luck for Chelsea. Even though home and away don't have an effect in a match, I have a little confidence that Chelsea can do it in this match.
Because this victory is very important for Chelsea to take advantage of their moment of revival when we know they have been in decline. Because in the EPL league there are always surprises where a team experiences mental decline but then they can recover without us expecting it. I don't mean to belittle Arsenal, but Chelsea can win because they need to bounce back and I believe Poch can recreate that winning mentality for Chelsea. Because he has good and talented players too.
