Many were surprised that Villas-Boas has started Gallas in every game this year given that he is 35, but Vertonghen insists the Spurs skipper is not past it.
"William is very experienced and with his experience he can be a very good player for us," Vertonghen said.
"He is our captain and an important player. He treats me like I am his little brother so that's why he is a very good captain.
"He always wants the best for me, even though we are both centre-backs. I really appreciate him."
