Santo believes the North Londoners will be a very good team if they remain committed throughout the season.
Coming into the game without their superstar Harry Kane, who was left out of the matchday squad for lacking match fitness, many gave Spurs a little chance against Pep Guardiola’s side.
Manchester City started on the front foot but could not convert their half chances into a potential goalscoring threat.
The game had the lift-off it deserved in the second half when Spurs took the lead on 55 minutes after a blistering counter-attack where Steven Bergwijn carried the ball forward and played it out to Son Hueing-min, who cut inside before curling home a sumptuous effort.
Speaking to the media after the game, Santo was excited with his side’s display in front of their home fans.
"It was good I think. The atmosphere was special off the hard work of the boys. They make any crowd proud when they work so hard,” he said.
"It was strong. We were lucky because they had chances but the boys held on and they stayed in the game.
“We knew it would be tough. After that first 20 minutes we did better and we started getting our chances. In the first half we didn't finish so good. When we should have shot on goal we didn't do it.
"Not only him [Japhet Tanganga]. In terms of shape and our organization the front three worked very hard and closed the gaps. It's very difficult to play against City with the way they build the first moment. It requires a lot of discipline so the boys did OK.
"I'm sure that with commitment and the talent we have, we will be a good team. We are in the process of that. I am learning every day and I am very proud of them, very proud."
