"Jack Wilshere is a superb, excellent and an amazing player and talent but I feel he is the reason for us playing poor, start of the season we played amazing and now too. I don't think he is too blame is just mentally we believe Jack is the saviour therefore all attacks must go through him. "Over-reliance". Santi Cazorla must be the focal of our team!"

Nail on the head

A culmination of many things, as you mention. The second string players obviously wanting to prove a point and keep their spots, Wenger finally realising that our players are not undroppable and finally some organisation in the team and proper tactics being applied.
