The 22-year-old is recovering from an ankle injury that he suffered in August and was expected to be out for around three months.
He told Marca: “I am touching the ball, working with intensity and each day I am getting better.
“I do not have a timescale, but within two or three weeks I expect to be working with the rest of the team.
“I will take it calmly, because I am not going to risk anything after the injury that I have had. What I want is to recover well.”
