Evans was basically blacklisted for being a rapist (conviction overturned he's not guilty of anything, other than being a scrote). Hughes and the other lad actually killed people but were allowed back into...
Not so sure. Look at what happened to Ched Evans until his conviction was overturned.
Johnson was actually completely guilty. Can't see any British club going anywhere near him. Imagine the shitstorm (and rightfully so in this case).
