Vertonghen already has half an eye on what could prove a decisive clash with the Reds at Anfield on March 30.
"We probably need a win, so we will go for that," the Belgium international said.
"It was a bad day for us when we lost 5-0 at home to Liverpool in December but that game didn't reflect our strengths compared with theirs.
"We beat them at home last year and we went 2-1 up at Anfield last March, where we were the better side (Spurs eventually lost 3-2). That was one of our better performances last season.
"We need to work on our shape and our movement and then the sharpness will be there. Tim now has a chance to work on our shape. Until now, he has done a very good job. The club and the players believe in him."
