The Spanish youth international is wanted by the Championship club on a season-long deal.
"At the moment nothing is confirmed," Canaries boss Chris Hughton told the Pink 'Un. "There has been that interest and we'll just see where that goes but nothing has yet been confirmed. It is an enquiry - that is all I would say.
"We'll certainly know more over the next day or two and then we have got a decision to make at the club on what we do on that one. I have to make that decision but I have five centre halves at the moment.
"He is a good young talent, he is young and he an injury last year that restricted his games. I think from memory he only played six or seven times in the first team and he is one that we would like to see how he develops but that is for the next day or two."
