Here in Germany, the salaries for referees are
FIFA accredited, €60.000
non-FIFA acc. , €50.000 (after 5 years in the Bundesliga).
Starting salary for Bundesliga, €40.000
Bundesliga 2, €25.000
On top of that, they'll get €3.800 for a BL1 or €2.000 for a BL2 game!
Serious money, and having seen the H96 goal against Cologne on Sunday, wouldn't say that the fans/clubs are getting much value for said money.
