The biggest shouts were
1. Penalty for us - and a pretty obvious one - ignored
2. High boot on our player - ignored
3. Penalty for them - clearly not a penalty even if you're being generous - ignored
Then we had the two dropped balls - one for Forest and one for Liverpool
Andy, they weren't the biggest shouts. Not if you believe there is systematic bias or corruption in PGMOL against Liverpool. If you believe there is corruption and bias (and maybe a conspiracy) against us then the biggest shouts were:
1. The decision not to award a penalty against Joe Gomez near the end.
2. The decision not to blow the whistle and end the game after Forest cleared the corner.
The first of these would have been really harsh on Liverpool, possibly an outrage, but would not have been so 'out of the ordinary' that a corrupt PGMOL could not have plausibly defended Tierney's decision. The second was a much easier decision for Tierney. If he'd blown his whistle after the initial clearance I doubt even you would have complained!
Both were real opportunities for Tierney to ensure Liverpool dropped either two points, or possibly three. Neither was taken.
That is what needs explaining.
