We stormed back from a goal down to lead 3-1 at half-time and then 4-1 before Chelsea hit back for 4-2, only for Nacer Chadli to strike a fifth goal on 78 minutes. John Terry's late third proved no more than a consolation.
Harry Kane's fine solo effort - his 17th in all competitions this season - got us back on level terms and crucially Danny Rose and Andros Townsend put us in the driving seat before the break.
Harry slotted home for 4-1 on 52 minutes before Chelsea's rally but Nacer's goal - the icing on the cake of his personal display - put the issue beyond doubt.
Victory lifted us above Arsenal into fifth as we stepped into 2015 and into the second half of the league campaign in style.
Harry and Nacer's combination work certainly caught the eye but asked about their contribution afterwards, Mauricio was quick to pay tribute to the full team.
"It’s true that Harry scored and Nacer scored but football is a team performance and it’s important all players in the starting 11, on the bench or out of the squad, we are a team and when we got this victory, it’s for everyone.
"I’m very happy. I’m pleased for our players and our supporters. It was a very important game, a very important three points. Everyone is happy."
Mauricio also highlighted the team's character after going a goal down.
"I think in the last few months we have started to show character and the right mentality," he said. "Every day we try to improve and we need to go step by step, to continue working hard and believe in our way."
And there was also a word for the fans, who generated an electric atmosphere. "It's great to feel this atmosphere and energy, when the fans shout and support the team it's a great atmosphere at White Hart Lane."
