Antonio Conte said Tottenham faced a season of "hard work" despite moving to within two points of a Champions League spot with a third successive Premier League win.
An outstanding goal by Lucas Moura helped propel fast-improving Spurs to victory over bottom club Norwich City.
Tottenham boss Conte, however, is not getting carried away after taking 10 points from his first four league games in charge.
"We have to build a solid base and a good foundation if we want to try to be competitive in the future and fight for something important," said the Italian.
