I think he's a shadow of who he was last year..
While I admit he is still class I think to sign him for big money now would be a signing on reputation and not on form.
For someone like Arsenal, who are desperate to get their season back on track quickly, they need someone who's going to come to the club and be at their best straight away, otherwise they could find themselves drifting off the pace for the CL spots.
Fantasy football measures your points based on basic stats.. passes, tackles, goals, assists, etc.. Arteta is still going to get those points (5th highest is surprising I admit but there you go..) .. but if you got points for times you'd single handedly rescued points for your team with moments of genius, not necessarily assists but just little sparks in midfield that have led to goals being scored, important goals... then Arteta would have a quarter of the points he'd have had last year.
When Everton played last year, if they were losing you always felt that Arteta would come up with something.. a moment of genius that would just turn the game... I look at them now and I just don't see that. I see a very solid team and a good midfield capable of upsetting... but from Arteta? Nah.. I see it more from Cahill, Pienaar or Fellaini than Arteta.
