Half an hour after Michael Vaughan resigned from the Test captaincy, Collingwood relinquished charge of the ODI squad because it was affecting his ability to enjoy the game. Collingwood told his wife on the night before his century against South Africa that it was time to go. He later explained, "I've found the extra workload to be very difficult [...]. It's mentally tiring, and that's the top and bottom of it. I want to have a smile on my face when I'm playing cricket, and, if I'd have kept going, I'm not sure that would have been the case."
