Blackburn was in the days before the oligarchs and the super clubs etc, and they had the richest owner who spent a then world record fee on Alan Shearer didn't they?
What Leicester are doing is nothing like what Blackburn did. Blackburn spent lots (comparatively) to give them a shot at the title. Only difference being it was a local businessman who funded it rather than some Arab or Russian billionaire.
Leicester have taken virtually the same squad that were bottom for most of last season to being genuine title contenders. It is ridiculous.
