Recent reports suggested the Gunners had made a bid of €8 million for the Brazilian striker and also approached los Blancos over the possibility of a loan deal for the Spain Under-21 starlet.
Morata has found first-team opportunities hard to come by at Real Madrid this season, while Pato's career has stalled since ending an injury-plagued spell with Milan to return to Brazil.
Arsene Wenger has made no secret of his desire to sign another striker to ease the burden on Olivier Giroud, but moved to quell the speculation ahead of Wednesday's Premier League clash with Hull City.
When asked whether he had enquired about the availability of Morata, Wenger replied: "There is no truth in that, that is all I can say. I have not been in touch with them."
