The two clubs have reached an agreement for the striker, but Amadeo Salvo says a problem with agents is delaying official confirmation.
Now, following former Valencia director Antonio Sese hinting that a deal had been struck, and current Los Che coach Miroslav Djukic seemingly resigned to losing Soldado, Salvo has confirmed a move is imminent.
"The agreement with Tottenham is total," Salvo is quoted as saying by Las Provincias.
However, the Che chief has admitted that the switch will not be completed until issues involving Soldado's representatives have been resolved.
"A problem with the agents has emerged," he added. "[Once resolved] he will go."
Elsewhere, Tottenham center back Bongani Khumalo has joined Championship side Doncaster Rovers on a season-long loan.
The South Africa international spent last term at Greek side PAOK. This will be his third spell in England following stints at Preston and Reading.
