I can see why he needed to view it again, l wouldn't call it "blatant" though.
Yes l do believe that some referees are incompetant, but in no way would l call any of them biased.
I'm sure that's the case. The problem arises that on that one occasion in a hundred when a player goes down seemingly feigning serious injury . . . and yet the ref waves play on.
Then all too late it is discovered that he is seriously hurt, cue possible court case . It is a problem though...
