Moving the discussion in here instead, due to moaning.
Don't think that's true. Watch it again a few times, we keep a good shape throughout. We react well defensively to the free kick, filling in for the sleeping Maguire/Shaw. McTominay helps out the defense by coming in and replacing Lindelof. He's then caught sleeping when Palasic makes the run, although you can see he looks left and notices him but is too slow to react in time as Palasic has the better acceleration.
Zappacosta got in far too easily this is true. But that's all down to the quick free kick as Shaw should be in Lindelofs position and he'd have done a better job getting closer to Zappacosta. But you can see in that move that the players understood what they needed to do and filled in correctly. The execution was also good, shape was decent throughout. We just failed with individual brain farts (again). What coaching would improve that? It's down to player focus and leadership on the pitch. Maguire should be the one barking at his defense to focus and get back when the free kick is given but he along with Shaw are sleeping.
Second goal was a clear foul on McTominay, pushed him over which actually hindered Shaw as well. Excellent header though.
