I'm willing to give somewhat of a pass to the sides for poor ball control given the deluge the match was played in. Still, neither side was convincing. That said, Arsenal is in fourth having played 3 top 6 sides, including 2 on the road. The goal they gave up was a broken play finished with a wonder strike, so can't be too upset about that.
You can see the difference in the side when Laca is in versus when he is out. He strings together so many more chances. Hopefully he is fit soon. You could also see that Chambers and Kola, while they didn't play poorly, especially defensively, didn't offer as much going forward as Tierney/Bellerin will. Arsenal has a lot of guys who are good at getting a yard of space in the box, even if the finishing hasn't been there yet. Add in service from those wingbacks and Arsenal could look a lot more dangerous.
Meanwhile, in the midfield, Guendouzi again impressed. He was ever present. Hopefully the stats back this up and it isn't just me noticing the hair. We looked a lot more compact with Torreira in there. The announcers commented on how there seems to be no larger disconnect between fan and locker room perception throughout the EPL than that with our captain and they were right. Xhaka was again unimpressive. He played a couple decent long balls and was fine defensively with Torreira covering, but looked a mess when Torreira was pulled out. Still not sure why the midfield going forward isn't three of Torreira, Willock, Guendouzi, and Ceballos, even accounting for the latter's rough showing today.
Ultimately, you never complain about a point at Old Trafford, but given the state of Man United, I couldn't help but feel like the performance was wanting.
