The 26-year-old is expected to leave Newcastle this summer after playing a starring role at Euro 2016 for host nation France, who finished runners-up in the competition.
Newcastle boss Rafael Benitez told the Shields Gazette that he did not know whether Sissoko would still be on Tyneside beyond the end of this summer's transfer window.
The player was primarily used on the Magpies' wing last season but caught attention at Euro 2016 for his performances in a more central midfield role.
And Hislop feels that he is best used in a number 10 position, thus suggesting that his first-team prospects could be stronger at Tottenham due to the fact he would not be competing with Arsenal wizard Mesut Ozil for a first-team shirt.
Asked which North London club he would be better suited to, Hislop told ESPN: "Right now, I'm thinking Spurs is a better fit than Arsenal. I feel his best position is just in behind the striker as an attacking midfielder.
"When you look at Arsenal, I think that's Ozil's best position as a number 10. As a result and almost by default, maybe Spurs is the better fit."
