Moss is a berk and should be struck off. initially he waved off the pen. After discussing with the linesman, he still wasnt sure that Lovren did touch the ball. However, he decides to give the pen anyway, even when he is NOT sure. A pen that he initially did not want to give. Pure pubbery....or corruption.
Same thing with the 2nd pen. initially he waved it away....then gives it after the linesman waves.
