izzo is a proven match fixer. initially the prosecutor asked for a ban of six years (yes, years), then the federation banned him for 1,5 years which was reduced to 6 months (yup, half a year, twelfth of the ban asked by the prosecutor) on appeal. half a year for match fixing with mafia involvement.
england isn't perfect by any means. that said, italian sports justice system is like a terrible joke.
(btw this may the ordinary justice sentenced izzo to five years in prison, pending appeal. he's a mafioso and he's still playing for monza.)
