I was less bothered by the timekeeping - it's a given. And I don't think he was the worst we have seen - that was Lahoz v Liverpool. But he was another in a long line of referees who allow the game to be ruined by allowing one team to commit numerous little fouls and punishing the team trying to win the game.
It was the way he allowed Everton to kick Haaland (in particular) without any punishment. In the incident that led to Haaland being booked - he had two of them hanging round his neck as he went for the header - clear penalty. Nothing done but when he goes in a touch too hard to make a tackle - immediate booking.
There was a later incident in the centre circle where No2 (who somehow had already been booked) came through the back of Haaland and in doing so stopped a breakaway - two reasons why it should have been a second booking - he then rolled around pretending to be hurt and miraculously the second yellow didn't appear.
Then walked off at an angle so it took him longer to get off the pitch! Do they realise how much of a knobhead it makes them look these players?!
