Tottenham boss Ange Postecoglou was delighted after their 2-1 win against Brighton.
Brennan Johnson struck the winner for Spurs in injury-time.
Postecoglou said: "It was a great finish for us and the supporters.
"It's a reward for our second half efforts but we weren't great in the first half. Part of that was because Brighton are a great team and we lacked some discipline.
"It's fair to say that we are still a work in progress but we had a world class player in Son [Heung-min], who makes the most difficult ball look simple to set up Brennan [Johnson].
"Going into the game we looked at the squad and knew we had the ability to change it up. It's fair to say that helped us.
"Brighton tried to contain us and looked a bit fatigued so it was good to be able to bring players on."
