Morata, 24, has emerged as Jose Mourinho's top target to bolster the United attack ahead of the upcoming season since Antoine Griezmann made a decision to continue one more season at Atletico Madrid.
It was reported earlier in the week that the Spanish striker had told the club he wanted to move after word reached him that Real had upped their asking price from £60m to £80m.
Morata, who recently but cut short his honeymoon to resolve his future, is expected to finally join Manchester United later on in the summer but this admission by Perez may mean that there is no agreement yet in place.
Just as Madrid looked close to a deal with United, the sudden transfer request from Cristiano Ronaldo broke off negotiations and Morata flew off for his holidays. "I have read that we have reached an agreement, I do not know how many million times, but it is not true".

And Fairley has played for three different teams over six National Football League seasons, passing physicals with all of them. With Fairley out, the Saints will lean on Sheldon Rankins , David Onyemata and Tyeler Davison as their top interior defenders.
Will Morata move to United? We are still in June and until 31 August there is no need to hurry.
Morata is already thought to have agreed personal terms ahead of a move to Old Trafford, but Jose Mourinho's side are understandably reluctant to part with such a high fee. James is a Madrid player and Madrid players do not leave when they want or when their parents or agents want.
