yeah, his positioning sucked indeed. besides szczesny, he was to blame for the first goal, iirc i even wrote it in the live thread. and i also think that he's rusty af, especially in the way he thinks. as
@JCK said, sometimes he had no idea where he passed the ball. still, i saw some glimpses of a solid holding mid, and some well-timed tackles too. yes, rabiot played like a rookie, but he's literally a rookie for us, so no surprises here.
i'm just saying that he wasn't all but hopeless. he got his shit together for the second half, and despite not playing a full 90 minutes since forever, his stamina was okay too. bad, but not hopelessly bad match overall.
