Italian star Andrea Pirlo is unsure whether he will be ready to make his New York City FC debut in Sunday's Major League Soccer clash with Orlando City at Yankee Stadium.

Juventus legend Pirlo has commenced training with his new club, but refused to confirm his availability for Sunday's fixture and a showdown with former AC Milan teammate Kaka.

"I do not know. It really depends on how things go day-to-day," Pirlo said through a translator.

"I've been on vacation for a month, I did work during that month and I am feeling well, but we'll see what happens on Sunday.

"The only thing that is left to do is to really get to the right physical condition in order to play at my best."
