Liverpool winning the league is a gold mine for the Premier League and the entire media.....Liverpool have a much bigger fanbase than Man City and Spurs..
Football is a business, worldwide Liverpool are one of the biggest supported teams (them and United are the big 2)...
A big percentage of Liverpool fans are bandwagon fans (they only really show interest when they think there gonna win something).... When they show interest, they subscribe to Sky Sports and BT to watch their team (same with PPV channels all over the world)..... They click on to articles online to read up on what they need to tell friends is their opinion... They buy newspapers they wouldn't normally.... More viewers and readers, means bigger advertising deals, and bigger TV deals for the PL...
Guarantee you Sky and BT have atleast 5 times the subscribers now then they had the year Leicester won the league...
So yes the Premier league has a financial reason to want to see Liverpool succeed... And the media have a financial reason to make light of offside goals, and diving that are bringing Liverpool success (and sure if all the pundits are biased Liverpool fans, everything is easily taken care of)...
