He was alright, better than normal, didn't have any huge decisions to make. Of course they were screaming every time Opoku went near it after being booked and he held his nerve well.
But, seriously, and not to sound churlish, but in the era of professional refs, should any of them be that out of shape?
A three or four mile run three times a week would be enough to keep a ref in relatively decent physical condition and that's the very least they should be doing if it's their job. Regular exercise is also shown to keep your mind sharp which is a key prerequisite for a ref I'd say. What's this fella doing between matches because it clearly isn't keeping himself in condition?
