The Belgian defender's claims, however, could not be more wrong.
Spurs head to Anfield this Sunday off the back of a 3-2 win against Southampton, a result that ended a run of four straight defeats for the club.
But Tim Sherwood's side are still nine points behind second-placed Liverpool and know the Reds have only lost once at home all season.
And Vertonghen believes the key reason for that is 27-year-old goal machine Suarez.
"Suarez," he told reporters. "Suarez is the reason for that.
"At the moment, he is up there as one of the best strikers in the world. I think he is the difference between the teams.
"[Daniel] Sturridge obviously is doing well and those two are very hard to stop."
The Uruguayan is certainly in the form of his life - but a fleeting mention of Sturridge and a complete disregard for the rest of the Liverpool team? Perhaps Vertonghen hasn't been watching Brendan Rodgers' side in action this season.
A key characteristic within the Reds' squad has been their collective unity. Steven Gerrard, Jordan Henderson and Jon Flanagan are as key to their success as Simon Mignolet, Philippe Coutinho and Raheem Sterling.
Compare that to the Spurs side, however, and you see where the real difference lies. Amongst the vast list of names both Andre Villas-Boas and Sherwood have selected this season, few have put together a consistently good run of games together.
Against Southampton, meanwhile, Christian Eriksen was the driving force behind their side. Without him, they simply would not have recovered from 2-0 down.
But as if that was not enough, the statistics provide a final nail in the coffin for Vertonghen's theory.
This season, Suarez has scored 28 league goals and made 11 assists. Take that out of the equation - and that's not to mention the time Suarez spent suspended, during which Liverpool topped the league for several weeks - and the Reds still have 14 more goals than Spurs and 18 more assists.
Is the Uruguayan alone the difference, then? Far from it.
