Clutching at straws here mate. Simply because he came to the city for an education doesn't automatically transfer any footballing allegiances.
In reality, he's just an incompetent referee as it is without trying to blame it on other things. He may have an issue with Everton* etc., but so could must referees.
The real issue is the abysmal standard of refereeing that we have and the closed shop PGMOL who facilitate their incompetence without any real accountability.
I saw the Sakho 'handball' last night and just laughed because I've gone beyond being surprised by it. No football fan in the world would say that was handball.
*replace Everton with any team.
