Valencia insist they are not looking to sell Juan Mata after renewed links with Manchester City.
Spanish media claim that Roberto Mancini is looking to pair Mata with his former Valencia team-mate David Silva, who moved to Eastlands last summer.
Mata, who was strongly linked to Barcelona last summer, is said to be attracting a great deal of attention from both Manchester clubs.
City are reported to have been keeping close tabs on Mata's displays in recent months.
But Valencia president Manuel Llorente has made it clear he is not looking to sell - having been forced to sell prized assets David Villa and Silva last year.
"The kid is un-negotiable because he is a key man in our project," Llorente told Provincias.
The player's agent and father, also named Juan, insists he has not had any contact with City.
"I have not spoken with City," he told skysports.com.
Spanish sources now claim that City could look at Mata's team-mate Pablo Hernandez as an alternative.
Liverpool are also said to be keen on the 25-year-old, who Valencia could be tempted to sell.
