Wenger’s side were then able to hold out the home side at White Hart Lane to go within four points of the Blues and even with second-placed Liverpool after a couple of tricky fixtures in the FA Cup and Champions League.

"It makes the next game very interesting. The win for Liverpool at Man Utd, and the fact that Man City won yesterday, it makes it very interesting.
"From time to time, it's important to know you cannot always be super-dominant in a season. And to win games when you're not is important."
