Don't write off Arsenal. You mentioned Tottenham... But Arsenal has done better than Tottenham this season. Currently at 6th place, they're above Tottenham and Manchester United ~ both of which you mentioned.
Arsenal, Tottenham and Utd - I think these three teams really are struggling to find their ground in this EPL. I am not expecting much from them. Sheff, Leicester even Wolves are doing far better than these big teams.
