Marseille have confirmed Valencia are interested in signing Taye Taiwo.
Taiwo has attracted the interest of a host of clubs across Europe after impressing at Stade Velodrome.
Valencia are in the market for a new left back with Fabio Aurelio set to join Liverpool and are thought to have made Taiwo their top target.
Marseille chairman Pape Diouf confirmed Valencia were keen on Taiwo, but insists no offer has been made for the Nigerian.
"That is true that Valencia has shown interest but, they have not made an offer," Diouf told France Provence.
"We haven't talked to the directors.
"For instance, we haven't given our agreement for his departure."
Diouf also revealed that they are close to agreeing a deal for Liverpool's Djibril Cisse.
Marseille have been chasing Cisse for some time and they have held talks with Liverpool officials over a possible loan switch.
Diouf believes the deal is close to being sealed with just a few minor details to be ironed out.
"We are closing on an agreement, we are on the right direction," added Diouf.
"There are only a few details remaining."
