How do you know he “deliberately instructed” him to do that? Locatelli and Kalulu were all over the place cleaning up, maybe David Luiz just thought the pitch felt softer out wide.
Because he was standing on left mid position almost allways, especially whenever Cambiaso drifting in when we're on the ball.
Motta is right there next to him on that side lol, if it wasn't a deliberate instruction to keep that position, he would been told to move or be subbed off.
He wasn't very mobile, but it was an odd tactical task he was given. His static lazy approach to movement was more evident when he was almost an AM just staying close to Vlahovic at times.
But the left role was more or less a deliberate way to be an extra outlet for short pass, overwhelm on the left and the idea was probably switch to the right. But nothing was happening on right either.
Really odd game tactically.
