He should be sent packing - not because of what he did yesterday - but just because he's shite.
Couldn't care less what players do in their spare time - it's fairly obvious that most if not all, certainly Scottish players, will have allegiances to either Rangers or Celtic, but as long as they do the business ON the park against whichever team they support, they can do whatever they like (within reason) off it.
Really nothing to see here.
