The Wellington coach said the decision to stay in Australia ahead of the game had paid dividends.
The Phoenix beat Macarthur 2-1 in Sydney last weekend in the first leg of their Australian trip.
“The long trip is difficult. If we had gone home and come back I think we would have been in all sorts,” he said.
“More importantly the time zone...even though there’s a five hour difference, it’s just that travel, and all those things are very important.”
The Phoenix’s six-point lead on the points table is likely to come under threat sooner rather than later.
Nearest rivals Central Coast Mariners and Melbourne Victory play each other on Sunday evening.
If there is a winner, Wellington’s lead will be cut to three.
The Phoenix return home to host Adelaide United next Sunday.
