Arsenal should not be resting on their laurels. Spurs are only 3 points off them in 5th place and we are only 2 points behind Spurs.
I think it's important that all 3 clubs don't dismiss Chelsea and Leicester. I think Leicester have to be taken seriously. I realise they have lost Mahrez and Kanté from their title winning squad but they still have a lot if very capable players and Rodgers seems to be getting a tune out of them.
We could really see all 3 clubs failing to make the top 4 this year. Having said that, the Spurs situation has been overblown and Man Utd are a Solskjaer sacking and one teansfer window away from fixing their problems.
I think we've seen enough from Emery now to suggest that he is not the right man for the job. I like the fact that he has dropped Özil, that's a necessary course of action; but there isn't much else about him that gives me confidence (his insistence on playing Xhaka no matter what is of particular annoyance for me).
Bear in mind though that we've had 3 defenders out since the beginning of the season, so he still has some cards to play.
