Newcastle manager Steve Bruce told BBC Sport: "I was delighted with the performance. I think we needed that. We needed to show what we're about. We had an awful five minutes where we gave an awful goal then they produced a good bit of quality to open us up.
"The way the players responded and played throughout... I thought we were the better team and had an edge and energy about us.
"I was determined I would pick a team who hadn't been away half way around the world and would be fresh. They deserved to win the game and it was the performance I was delighted with."
Tottenham manager Jose Mourinho told BBC Radio 5 Live: "I am frustrated. We needed to win the match and we came to win. We were not far from winning it but, at the same time, we created some instability on the game with so many individual defensive mistakes that we made. We always gave Newcastle a chance to be in the game.
"Of course, we had the biggest chance of the game to make it 3-1 and kill it, then we concede a goal the next minute.
"Looking at the second goal, it's easy to understand because there's three different moments - the cross, the ball at the far post where they won it, and then the ball in the face of the goal where our two centre-backs were in position. You can analyse it easily."
