It's all of them. For some reason I can't post a screenshot but if you stop it at 2:41, the Sevilla player has the ball about 5 yards inside his own half and there isn't a rag player near him. They're all running back towards their own goal and no one is putting any pressure on him. We'd be converging on the ball carrier in numbers but they're all retreating, leaving him the freedom of the park.
Even worse, they've not blocked any of the channels - they're running back like headless chickens - and nor have the defenders moved up to cover the Sevilla forwards. The lad's got so many options;
- he can put it over the top to Correa on the left touchline, because Valencia is way out of position;
- he can play it forward to Ben Vedder, who's straight ahead of him and completely open;
- he can play it to Sarabia on the right, who Pogba has let go without tracking;
- he's also got the player just in front of him and the two players to his left.
There's no evidence of any coaching or football intelligence there. No one is thinking "We've got to put pressure on the player with the ball" or "I need to block off the possible pass and put myself in a position to intercept it". They've clearly not been drilled at all in the way that someone like Pep or Benitez would drill their players in detail to cover various eventualities. It's simply astonishing.
