The 23-year-old has been linked with a return to Spain.
“No-one likes to play in the Championship but I’m only thinking about fulfilling my contract,” he said.
“The team has a great budget and I am sure that if they do things well from the beginning, we can create a team of the level of Aston Villa.
“I like the city and I am very happy in England. Today, I see myself playing next season at Newcastle.”
