I did not see Arsenal successfully defeated Man City with that score and maybe you were wrong to see. The last time the two met in the English League Arsenal won the match with 1-0 at their own home and at the Community Shield Cup they drew. This season both of them only met twice so that Man City was still enough to be favored to win the match. Of course the match will change where the two coaches will study the strategies with each other, both Arsenal and Man City need a victory in the match because they will open the way to win the league.
In all cases Man City is far more favored to come out as champions, because they are far more potential to win matches at home, Arteta has the opportunity to hold Pep Guardiola's draw but the opportunity is still quite small. Now the condition of Man City players is almost fully fit so that their strength will be much stronger, different like matches that take place at home to Arsenal because Man City is not strengthened by creative midfielders like De Bruyne.
People have predicted differently in this match; some predict a draw, some predict Manchester City to win, and others predict Arsenal to win, but to me, I’m still yet to see the winner of this match as both of these two clubs are in their best form. I don’t really see any sign of weakness in either of them, so therefore I can’t predict who will win, but if I’m to give someone a chance of winning this match, I will say Arsenal, even if Manchester City are going to play at home, because Arsenal are at the top of the table currently. I don't think this will make them dominate the match, and they will do everything in their power to see that they maintain that position.
Anything that will make them drop in that position will reduce their chance of getting the ticket, and that’s why they won’t make the wrong move. I believe Arteta will try his possible best, like he has been doing so far. I think he will do so this time, so let's see who is going to be the champion in this game because seriously, the match is going to be tough and both are doing well, so we can just conclude the winner yet.
