Everton have been very impressive.
I thought they'd suffer from Moyes departure, but looks like they got a more than adequate replacement in Martinez.
I expected them to suffer from Fellaini's departure, but they've actually strengthened their starting lineup and squad with the addition of Lukaku, Barry and McCarthy and the emergence of Barkley.
And they play like a team, a unit. They win at OT and Swansea. They outplay Arsenal at the Emirates. Only one defeat after 17 games.
Very impressive.
