The Manchester United legend, who had four games in charge of the Red Devils in a caretaker capacity four years ago, is preparing his side for Thursday's clash with China.
Despite playing in countless big games during his illustrious career, and also spending time at United as part of the backroom staff, Giggs insists that nothing compares to how he is feeling ahead of the China Cup opener in Nanning.
"I'll be much more nervous tomorrow," he told reporters. "As a player you want a little bit of nerves but generally speaking I never really got nervous. Coaching and management is completely different.
"As a player you're quite selfish and you're just making sure you're doing your job in the team. As a manager and a coach there are so many things to think about; you are constantly going through your mind. There are lots of things going around in my head, it is completely different from being a player."
Wales, boosted by star man Gareth Bale in their ranks, will also face either Czech Republic or Uruguay during their time in the Far East.
