The former Spurs midfielder revealed he had text club chairman Daniel Levy telling him the winger would be perfect.
The 26-year-old has been a star for the Dutch club and scored 21 goals in all competitions last season.
While working as a pundit for Studio Voetbal, van der Vaart said: “I really hope he goes to Tottenham Hotspur. I sent a message today to Levy, I said ‘get Ziyech after this season’. I am convinced that he will become a sensation in London.”
There was plenty of interest in him over the summer with Arsenal and Liverpool thought to be keen.
A move never materialised and he signed a new contract with the club, which then removed a previous £26million release clause.
Ziyech has again started the season well with six goals to his name and can expect clubs to renew interest next summer.
