Agree with all of that. Said something similar on the old OA. They basically had a free run almost for the first 3 months of last season because no one took them serious enough. By the time teams took notice, Leicester were in full beast mode.
This season is going to be very tough for them. Teams will be aware of their counter attacking style of play and make it much tougher. They might as well go as far as they can in the CL for the prestige, and the fact they may not get there again for a very long time, if at all.
