Reyes is currently on loan at Spanish giants Real Madrid.
He told Marca: “If I do not end up staying then I will try to look for a solution and if I can stay then that would be much better. It would not be a disaster if I do not though.
“I have been trying to prove myself since I arrived and now the end of the season is approaching and I have to show that I am worth keeping.
“But I am staying calm because the club has faith in me and I have faith in them and at the end of the season we can sit down and talk.
“I wanted to play here and now I have.”
