Spurs defender Vertonghen: Beating Man Utd, Arsenal a highlight
The Belgian enjoyed both wins.
"The win against Arsenal at home was great. That was when we really felt like a team together with the supporters," he told the Spurs website.
"It was a great game for us. The win at Old Trafford as well. The first half that day was probably our best half of the season, we were unbelievable.
"To win that was very special. It was a great feeling to beat Arsenal. It was my first North London derby at White Hart Lane and everyone was so happy afterwards."
