Just got a TSN notification. Zambrano is out as Head out and Herdman is in
EDIT
Herdman gave a good talk today.
The nuggets of info that were new to me, if I understood them correctly, were:
Canada brings a full-sized sword with "Qatar 2022" inscribed on the blade, and they stick it in the centre of the field before each match - presumably on the day-before training/walkthrough. He showed a video of Vitoria plunging the sword, and Herdman said some good words about his up-and-down trajectory with the national team and how he has grown into a leadership role.
