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
I am baffled by people having a problem with the first booking. Having a problem with Tsimikas not getting booked is fine, but Young stuck his leg out and initiates knee on knee contact to bring a winger down and stop an attack. That’s always a yellow.
A Liverpool player not getting booked several minutes later for a similar challenge is totally irrelevant to the question of whether Young’s is a yellow.
