Davis to Hoedt to Romeu back to Hoedt.
It was the first pass that created the problem. Davis had options forward. Hoedt had only Romeu who was closed down and then went back to Hoedt, who did the rest.
Davis didn't even look to go forward, just did the easy backwards thing.
Which is probably why Pied was so far out of position, because he was going forward waiting for a ball that never came.
