The London side have made the 28-year-old forward one of their top transfer targets this summer and are believed to be in negotiations with the Spanish team at the moment.
Valencia are believed to want the full £26m needed to trigger a release clause in the contract of Soldado, who netted 30 goals in 46 appearances last season.
And Spurs are believed to be confident of landing the Spanish international but the player himself is refusing to comment on the prospective move.
"I do not know what is going on at the moment," he said. "At the moment, I cannot say anything.
"We will wait to see what happens. When the right time comes, I will speak, as I always have done."
Spurs have already signed Brazilian midfielder Paulinho and Belgian winger Nacer Chadli this summer and will be hoping to make Soldado their third acquisition.
