Villas-Boas claimed Lennon's winner at Sunderland was exactly the reason the 25-year-old had been given a new four-year contract earlier this season.
"It was a beautiful goal," Villas-Boas told Spurs TV Online.
"It was a moment of magic from Lennon, a player who is a credit.
"This season, he's showing that he's on another level.
"He signed his contract with us, he's committed and always gives everything for the team. It was a great goal, great inspiration."
