Worst nickname in football, or any sport. Fuck him.
As I've said before, his nickname "The Ox" is as much driven by ease of use, as much as any nominative determinism or anthropomorphic comparison to his playing style or physicality.
His fucking name is "Oxlade-Chamberlain".
Who the fuck wants to type that out? And given the first two letters of that 18 character pain in the arse name are "O" and "X" it's quite understandable that it's shortened to "Ox" or "The Ox"
He'd be called it if he worked in PC World or Greggs too.
