I agree about especially one thing that Arsenal are still in no condition to be a little complacent in their games.
Because the point gap with Manchester City isn't too big. It might seem like eight points but Arsenal played one more game than them so far. If Manchester City win that missing game it will only be five points. It wouldn't be a too big deal for Manchester City to catch up with them if Arsenal start making mistakes. I'm aware of another thing that Manchester City are fighting for the Champions League title on one hand. But I think they can manage to balance these tournaments at the same time as of now.
I still hope to see Arsenal as the champions this season because they really deserve it. Their game against Manchester City in Etihad will also be really critical for this goal.
That's the trouble they have, they are doing great and all but they are still followed by City so closely. This happened to City so many times, they were leading the league and followed by Liverpool until the very last game, it is fun to see finally that City is the one that is doing the chasing.
I have to say it's not an easy task to follow the leader neither, Sure arsenal needs to be careful and win every game in order to not lose their spot, but even if they lose one game, they could still be the champions. However, City doesn't even have that chance, they need to win every game, one loss and the point difference could become too much to overcome, so their job is harder.
