"It looked like this was going to be our season, but it's turned out very differently from what we expected," said the Spanish striker. "I don't think Rafa will leave, especially halfway through the season.
"He still has four years to run on his contract, and he would not leave through the back door.
"Were he to leave, it would be with the team at the top. He's been given time, space and full control of every area of the club.
"Rafa wouldn't be able to enjoy the same benefits elsewhere."
