Tottenham's Belgian star, set to feature against Wales on Sunday, emphasised his determination to help the club into the Champions League spots.
Spurs defender Jan Vertonghen has stated that the squad are still confident of mounting a challenge for finishing in the Champions League places, despite struggling down in 12th place in the Premier League.
Vertonghen started on the bench in Tottenham's last game against Stoke, a disappointing loss at White Hart Lane, and has been in and out of the side for much of the league campaign, but remains passionate in taking an active role in trying to galvanise the side into moving up the league table.
Admitting that their recent form has been poor, the 27-year-old nevertheless asserted that those Champions League spots remain the target, and that the players and staff are set to get together after the international break and thrash out the problems in a meeting in an effort to get back on track.
"It's not good enough, but we are working hard to get to where we want to be,” Vertonghen said. “We want to be in the top four. We are looking for our best form.
“At the start of the season there where seven or eight teams wanting (to finish) top four, and two or three will be disappointed. I hope it's not us. I am confident we can finish in the top four.
“After this week we need to talk. Belief is still there. Hopefully we can be honest with each other, and turn things around."
