Tend to come down the middle on this: yes, on the balance of play we deserved to be at least a goal up, but to say we should have been three or four up is stretching it. That second half was as inert a performance as you'll see - really poor. A draw would probably have been the right result, but that's football - you don't always get what you deserve, and sometimes you get more.
Gloucester seemed a friendly club, anyway. Good luck with the move back home.
