The Reds boss arrived in Bangkok with his team on Thursday and, though he was aware how passionate United fans were in Asia, he was still taken aback by the reception.
"The amount of people who were at the airport was incredible and the excitement when we arrived was like The Beatles – it was something else," Moyes told MUTV.
"There are fans in and outside the hotel and everywhere we go. It just shows the power of United. I don’t know if I’ll ever get used to it!."
Moyes also discussed Wayne Rooney’s injury and you can watch the full interview with Stewart Gardner on MUTV at 10:00 BST.
