Newcastle United boss Alan Pardew says no offers have arrived for Xisco.
The Spanish striker was linked with Middlesbrough.
But Pardew told the Evening Chronicle: "I've not heard any news on Xisco, I was surprised to hear the story.
"There has been no contact with Middlesbrough at all.
"We have contacted a number of Spanish teams to see if they are interested.
"He's a lovely lad and popular with players here. He's lost his way a bit.
"I've sat down and told him that if nothing comes out in the transfer window this time, he will stay and we will try to get him back on the scene again.
"We'll work with him. Sometimes it's not about the attitude of the player, it's about the attitude of the club as well, and we'll work him. If he's prepared to change things a bit, I'm prepared to as well."
