Tottenham could make history and win their first Premier League title if they snatch Hakim Ziyech from bitter rivals Chelsea, according to their former player Rafael van der Vaart.
Antonio Conte's side have made a solid start to the season and sit third after 13 games - five points behind leaders Arsenal.
Chelsea, who are sixth in the table, have barely used Hakim Ziyech this season - with the Moroccan international only making one start so far this campaign.
'Hakim Ziyech has to join Tottenham,' Van der Vaart told Ziggo Sport during their Champions League coverage on Wednesday.
