This is absolute nonsense. Go and watch the goal again. Rodri plays a regulation ball back to Otamendi who, under minimal pressure miscontrols, panics and fires an absolute bullet pass back to Rodri, who is being closed down by 3 players. Rodri controls it brilliantly, realises there's only 1 player open to pass to, Otamendi, but Nico being Nico he's not expecting it, Modric coming from his blindside knows it's the only place he can pass, and the interception happens.
Their counter attack is caused by 1 player, and it's not Rodri and he sure as fuck wasn't panicking or thinking slowly.
Otamendi takes a heavy touch. Otamendi panics. Otamendi fires a pass to a player being covered by 3 defenders, Otamendi doesn't anticipate the ball coming back to him. Otamendi dives in and takes himself out of the game without getting man or ball.
Sorry, but there's no world in which that goal is Rodri's fault, and that's obvious before moving onto Walker's...whatever that was.
I've watched this back ten times now and each one I'm even more confused how Walker doesn't manage to stop this. Not getting anything on the ball from the position he's in legitimately seems impossible.
