Liverpool have benefited from referees with shite game management atleast 3 times in recent memory, to my mind.
As well as against us: Playing on when two handballs have occurred and the team who didn't have possession has sprang a counter off the back of it. How can you play advantage to the team that wouldn't have had the ball in the first place?
The Fulham ruled out goal, rolling ball free kick, with Fullham players appealing, ref allows Liverpool to play on. Liverpool just take the ball up the other end and score.
The corner against Barca I feel a lot of refs would have more carefully managed, when TAA came back on to pitch as if to hand over the corner duty, he could have blown his whistle as most would, as if to say hurry up/stop pissing about and get back in position. This would have got the attention of the Barca players who were expecting the handover.
They are a shithouse team and "it's tactical", it shows a certain dishonesty to their game that should be recognised.
