I'm not really one to blame refs or stir the pot in that regard. However, his performance today was absolutely shocking. Something was clearly amiss. He let way too much go for Arsenal (their players taking ages for corners, their players taking a long time for free kicks, their players going down too easily, their players slowing the game down deliberately in an unsportsmanlike fashion, their soft penalty that shouldn't have been given) and didn't give us enough (Saliba fouling one of our players in a build up with no card received, Bruno being mugged from behind and not getting a free kick on the edge of their box, many of our players receiving soft yellows whilst the same doesn't go the other way), and so on.
A very dislikeable performance from him.
It makes our victory even sweeter. We had to play against this referee today. He didn't control the game, he tilted the tables in their favour. Would not shock me one bit if there was more to this. This was more than poor.
