Roberto Mancini's team have won all of their league games at the Etihad Stadium this season, but Modric believes that his side can approach the fixture positively.
The Croatian international said: "We are going there with a positive mindset and we will try to win the game.
"We try to do that against every opponent. I think we are that good that we can go there and win."
Tottenham are in third place, five points behind league leaders Manchester City.
