Being subjective he calls what he sees, he's super fit and usually in a good position to see clearly, applies the rules as he sees them and I don't think he has a bias to any team in particular, even if it does appear that way to both sets of fans at the time.
He does not make any team win or lose a game and if you put him in a position to make a call then you can't complain at what he sees.
Reffing is an unenviable job in any sport but we wouldn't have a game without them.
I'm as guilty as anyone at bagging them during a game but that's emotion and passion getting the better of me.
Give the guys a break, I honestly believe that they do the best job they can
