Simoncelli has acknowledged the encounter was in doubt because of conditions set by the Asian Football Confederation, which included the use of foreign referees as opposed to Italian.
"Milan vs. Como will be played in Perth on February 8 as scheduled," Simoncelli told Mediaset on Thursday before the Italian Supercup semifinal between AC Milan and Napoli in Riyad.
"Yesterday I met with [FIFA president Gianni] Infantino in Doha and I had a cordial meeting.
"We had some doubts regarding certain conditions the AFC had set, which we considered impractical, especially regarding the referees. They have imposed to have foreign referees and we have great trust in Italian referees. We didn't feel like complying to this, let's say, AFC request.
"I spoke personally with [chairman of FIFA Referees Committee Pierluigi] Collina and he gave me extensive assurances about the quality of Asian referees; he has already in mind one or several referees of very high level that can officiate the game. That has reassured us.
"This condition, which was the most difficult to accept, we will accept. We will work out the rest in the coming days regarding the organisation of the game."

Spain's LaLiga had wanted to stage the league game between Villarreal and Barcelona in Miami in December but called it off due to the reaction in Spain to the decision to hold a league fixture on foreign soil.
Serie A got the approval of the two clubs, the Italian Footbal Federation (FIGC), UEFA, FIFA, the Asian Football Confederation and Football Australia for the match to be played Down Under.
