Yeah, I saw a video of the ~3 minutes between the missed Gordon foul that resulted in TAA's booking and the challenge they wanted a second yellow for, and as well as that Gordon kicking the ball away, Joelinton (I think) also moves himself in front of a Liverpool FK to stop it being taken quickly, all in that little spell. Like I said upthread, if you're going to set the bar low with the TAA yellow, it's particularly frustrating to see that almost immediately forgotten.
And the other thing that came from that clip is that I thought we were supposed to be automatically cautioning players who ask for a caution, as we saw when a number of players including MacAllister were booked in GW1? In which case, Brooks again missed a number of Newcastle cautions when TAA fouled Gordon and a number of players and bench occupants went crazy appealing for the second yellow. Including the captain Trippier who would therefore have potentially seen a second yellow himself when he went on to get booked in the second half.
That's always the problem with directive like this - performatively enforced for the first week, or for the first offence in a game, and then functionally ignored afterwards. In isolation, I have no real problem with TAA being booked there, and with Nunez again for the same in the second half if we're setting a standard to crack down on that. But fans can have no faith in this kind of thing when it's applied selectively or unfairly, as was the case in this game.
