People who mention other players and club's smear campaign against them, miss one crucial difference:
These players (like FDJ in the past) did not do anything wrong, other than not wanting to go.
(of course that also can be wrong on several different ways depending on the case, but I will leave that aside now)
Stegen doesn't do that only. He has reached another tier already with his actions of retaliation against the club.
Using a medical consent against club's FFP policy is a whole new level, and something never done before.
He should be punished in an exemplary way, so no one else ever thinks of trying that in the future
