Watch the 2nd goal in that video (the one that makes it 2-0 Atletico). In the build up, there is probably 10 players grouped together within about 10 yards of each other around 0.49-0.50
I appreciate that is player v player, but its like a school-ground there... the Atletico player top right who was giving the team width, for whatever reason decides to run back toward the halfway line!
Half of the Barca back 4 has gone missing, the other 2, somehow fail to note the runner coming toward them and are way to late to react to even get close enough to stop a shot going in.
Look at 0.52, 7 Barca players, 5 Atletico (not including the Barca keeper) all in shot, within yards of each other. What the hell is that all about, it looks a mess. Its like the players are just playing the ball and not position / being spatially aware.
I know its just 1 moment to pick out in the videos, but it looks like a bunch of 8 year olds chasing the ball round a park. I also appreciate that its player v player and I dont know what tactic settings either player has selected, but still, that sort of thing sticks out like a sore thumb.
1.25 in that video, the buildup to the next goal, again its a limited view of it all - but the bunching at the top of the screen seems a bit much to me. The ref is in acres of space in the middle

But again having all those midfielders grouped together like that caused the problems there.. seems a bit much, or maybe the pitch scale isnt right. Im being very critical and i appreciate that, but these are things that stick out to me on first look so id rather type them up, than ignore them.
The Neymar volley made me cringe, that was tapered to be like that the minute the ball started to ping about on a string.
Just some thoughts that crop into my head, I dont overthink before I type so am happy to be called wrong.
