The 17-year-old midfielder was watched by Sir Alex Ferguson's scouts in March after he rose to prominence by being named as the player of Copa Atletico.
"I would not accept a loan deal because that would be hard for me," he told AS.
"I have had a chance to leave before and I have not done so because my dream has always been to stay here and be a success with Atletico de Madrid.
"Now I hope that one day Cholo (coach Diego Simeone) has confidence in me and I can show him that I am ready.
"I am conscious that I am still only 17 and that I have to work hard in order to succeed."
