Jan Vertonghen believes that Gareth Bale is in the "form of his life"

Tottenham Hotspur defender Jan Vertonghen believes that Gareth Bale is in the "form of his life" following his brace against Lyon.

The 23-year-old has scored six goals in his last four games for Andre Villas-Boas's side and has given them a crucial lead in their Europa League tie.

Vertonghen told UEFA.com: "Bale is probably in the best form of his life. He's scored our last six goals as a winger that's unbelievable. I'm glad I'm playing with him and not against him.

"We will be fresh for the second leg because we don't have a game this weekend and we want to do something in Europe so I hope we go through."

The second leg of their Europa League knockout tie with Lyon takes place next week on February 21.
