Speaking on Spanish radio on Tuesday, Perez revealed former United manager Sir Alex Ferguson had approached Ancelotti about taking over at Old Trafford but the Italian coach had already agreed to join Real.
According to Perez, Ferguson then chose Moyes to replace him with the younger Scotsman failing to see out the season, as he was sacked in April.
"Manchester United wanted him last year," Perez told COPE.
"He told me that Ferguson asked him to be his replacement.
"Possibly United wanted him this year (as well) but I don't know. I can only assure you that they wanted him last year."
"No. I have read that but the season was already good" Real's president said.
"Winning is always better and can consolidate complicated situations but it was not our case.
"We have a project that I just started with a new coach. We will continue to improve but we need time and stability."
