It is understood that Brighton boss Gus Poyet has expressed an interest in taking his highly-rated countryman to the Amex Stadium.
However, it is thought that 27-year-old Fernandez - currently at Malaga - would prefer a move to the top-flight and there is interest.
Norwich City are amongst the clubs taking a keen interest, whilst Southampton are also believed to be in the reckoning.
The Saints' record signing Gaston Ramirez is understood to have recommended Fernandez to his employers, who are now taking notice.
It is believed that Fernandez could be available on loan from Malaga - but they would want an agreement for that to become permanent in the summer.
Agent Barry McIntosh, who has the UK mandate for Fernandez, confirmed that there was strong interest in England.
"Sebastian wants to come to England and I can confirm I have had several conversations with a number of clubs," he told Sky Sports.
"We are hopeful something can be done in the next couple of weeks."
