Valencia have reportedly targeted Zenit St Petersburg defender Ezequiel Garay as a possible candidate to replace Nicolas Otamendi.
After months of speculation, Nuno Esprito Santo's side are set to lose Otamendi after they agreed a fee with Manchester City for the 27-year-old.
However, AS claims that Valencia are ready to move quickly to fill the void in their squad, but a potential move for Garay, who moved to Zenit from Benfica last summer, could hinge on whether they secure a spot in the Champions League group stage.
The report suggests that Valencia also hold an interest in Stuttgart defender Antonio Rudiger, who is rumoured to be close to joining Roma.
