Wimmer was brought to Spurs from Cologne last summer, and he has mainly been used as a reserve so far.
The 23-year-old made only 10 Premier League appearances this season, but he has still impressed Vertonghen with his initial showings.
"Kevin did great whenever he came in, he fitted in perfectly," Vertonghen said. "There was never a doubt. Kevin is a great player and he did what everyone expected of him.”
Wimmer’s best run in Mauricio Pochettino’s side was when Vertonghen was ruled out with injury.
Vertonghen missed three months of the season with a knee injury which he picked up back in January, and Wimmer filled in at the heart of Spurs’ defence.
Wimmer partnered Toby Alderweireld and he looked perfectly comfortable, as he helped Spurs push Leicester City for the title.
However, as soon as Vertonghen was back fit, Wimmer was dropped back to the substitutes’ bench - and he has only made one appearance since the start of April.
Wimmer will be hoping to play a more prominent part next season, but his task of forcing his way into the Lilywhites’ team is a very tough one.
