Just because Liverpool fans developed an inflated sense of entitlement, it doesn’t mean that all other clubs fans have.
Continued success has to be earned & Utd haven’t done enough over the past 5 years to have any such expectations regardless of money spent.
The transfer fees & the wages are a reflection of the PL’s popularity and ability to market itself. Perhaps less to do with the players abilities. But think what it would actually cost to persuade a Toni Kroos, a Neymar, an Isco or Messi/Ronaldo to come & play in England. That puts someone like Fellaini’s fee & wages in perspective.
