The ironic thing is that Wenger will probably see Leicesters success last season as a validation of his own principles. Does anyone actually think he will study what they did and see if there are lessons to be learnt in style, personnel or training. He will rather most likely see that it proves you dont need to spend tons to win the league. Hence more scouting the lower leagues of Europe for the next big thing. He never learns it not just bad luck.
