Danilo challenged the other guy when he received the ball, but when Soriano picked it up, Danilo was closer to goal and started to run (jog) back already. Instead of closing down strong, he immediately looked at Rabiot who was also jogging with no immediate threat on his side. We set up into a 5 man backline before the entry pass, and 2 mids infront. De Sciglio was too far wide too, for a "RCB". De Ligt came out to pick up the immediate threat, because no one else was gonna, and he relied on Chiellini and MDS there. If anything, he should have come out sooner imo
