See I fundamentally disagree with the statement.

Whilst consistency across all games is difficult we can at least aim for constancy within the current match. Once the tone is set by letting Tsimikas fouls go then you have to keep that up

To be fair the first was never a yellow.

Tsimikas had already committed three fouls, one of which to stop a break and yet somehow Young’s first foul (which was in the Liverpool half) was a yellow.

The biggest issues with refs isn’t the clangers as VAR is slowly fixing that, it’s the inconsistency in the small decisions, an inconsistency that tends to favour the bigger teams
