Dembele has been Spurs' utility man throughout his time at White Hart Lane, with much debate around what his best position actually is.
The Belgian international has played as a shield in front of the defence and as an attacking midfielder this campaign, but Vertonghen feels he could even be suited to a role anywhere down the right-hand side.
“I don’t know [his best position] because he’s very strong defensively as well,” the central defender said. “With a good No 6 next to him he can do what he did for two seasons.
“I don’t know what his best position is - I think he can play right wing and right full-back because he has this strength in him that no-one can pass him. He’s just one of those players that you want in your team.”
Dembele's chances of breaking in at right-back look limited after Kyle Walker's return to fitness, but he could have more luck down the right-wing.
At the moment the likes of Andros Townsend and Erik Lamela are fighting it out for a place in that position, but neither have really hit top form.
It means that Vertonghen's suggestion could actually solve a problem within the squad, but whether Mauricio Pochettino will choose to heed the defender's advice remains to be seen.
Dembele has been in sparkling form over the last two fixtures playing in a more advanced role, behind the striker, and he is likely to be hoping to tie that position down rather than having to be moved to an unfamiliar right-wing spot.
