The striker admitted on Thursday that he is open to a move away from Real Madrid if he continues to find first-team chances hard to come by, with the Gunners reportedly interested
The young striker revealed on Thursday that he would be open to a move away from Santiago Bernabeu if he was afford a "relevant role" at the club.
And Arsenal have been touted as an interested party following Theo Walcott's season-ending injury, but Ancelotti considers the matter closed.
"My idea hasn't changed. Morata will stay. He hasn't asked to leave, either. I'm happy with him," Ancelotti told reporters.
Ancelotti's Madrid take on Espanyol next, and the manager says a win is vital if they are to take advantage of Atletico Madrid's game with Barcelona.
The joint Liga leaders lock horns at the Vicente Calderon on Saturday and Ancelotti is eager to take advantage of one or both of their title rivals dropping valuable points.
"Barca or Atleti? I don't know what result would be best for us. They can't both lose. We have to win to close the gap," Ancelotti told a press conference.
Madrid secured a comfortable 2-0 first-leg win over Osasuna in the Copa del Rey on Thursday thanks to goals from Karim Benzema and Jese Rodriguez, and Ancelotti was quick to praise the young Spaniard's form.
"[Jese] had a great game. He worked a lot. He's an important player, in a good moment," he added. "The game was good defensively. We didn't commit any fouls. The defenders worked well together.
"We're close to the next round. The game in Pamplona will not be easy, so this was a good result."
