I don't blame Mario "overated" Götze for staying his hoke ass put. As a club, Bayern are perhap the most structurally stable in top flight European football. They own a massive, fully paid for, stadium that they manage to fill on average. They have a massive annual turnover, with little to no debt (unlike say RM/Barça/United). They lord over their own personal fiefdom aka the Bundesliga, with rivals ready to feed them their top talents without resistance. They challenge for every title they compete for, and annualy progress deeply in their European campaigns. All in all, they are a club most players would ideally play for.
Götze gets paid a handsome wage at Bayern by just mailing in his performances. Why take a paycut to join Juve with the added pressure of being the difference making marqee signing? He's just playing it smart, but at the same this shows he aint got the testicular fortitude to justify his hype.
