This will be game of that week for sure! However, for me , it's a bit hard to predict because I do like Arsenal a lot but I also can't ignore City so the most likely outcome should be a draw ? or Arsenal to win because I do have a bit more faith in Arsenal to win than I have in City.
If it's a draw , I think the score will be 2-2 and first half should be over 1.5 goals or even both teams to score.
If Arsenal wins , then we have a 3-1 with 2-0 in first half for Arsenal. This are my 2 predictions on this and now I'm heading to post it. <3
Another great contest guys!

Exactly because both teams past performances seems quite the same. But just like as you mentioned that is the real truth about it because Arsenal is playing home even though Manchester city performance this season is not like as it used to be before, so given Arsenal home win or draw might likely be the best option for this game.
Honestly, I don't really know what to predict in this contest right now, that why I have not done my prediction yet. But hopefully before the end of this week I will definitely try luck on the thread, to see if I can get a win this time Lol.
