Spurs climbed to fourth in the Barclays Premier League after Vertonghen fired them to a 1-0 triumph with his first goal in the competition at White Hart Lane on Sunday.
Bale has been sidelined for two weeks with a hamstring injury and failed to make the squad against the Swans and Tottenham are criticised for their lack of penetration in the Wales winger's absence.
But Vertonghen, a £12million summer signing from Ajax, believes Clint Dempsey has proved a capable deputy.
"Maybe we needed a little more width on the pitch but Clint has replaced Gareth very well, like he has done with all the strikers already," he said.
"Of course Gareth is a world class player, but we did well without him.
"We have a big squad but have had too many injuries. But even without those players we've played quite well. When everybody comes back we'll have a very strong team."
