Spurs lost 6-0 and 5-1 to Premier League champions City last term under Pochettino's predecessors Andre Villas-Boas and Tim Sherwood, but the Argentinian has wiped those results from his memory.
"The reality is I don't remember the results," Pochettino said.
"This is another season, another philosophy, another game and we need to arrive on Saturday with the idea to believe in our philosophy and style and try to get the points.
"It's history and it's a different game, different players.
"It's not important now to think in the past
It's important to look forward.
"I don't have any concerns about these results."
Spurs are unbeaten away from home this term, while City have won one and drawn one of their three games at the Etihad so far.
Pochettino travels with optimism.
He added: "We arrive in a good moment
After our victory against Southampton we need to keep the momentum, to reproduce the same actions and to try to get the three points."
Former City striker Emmanuel Adebayor has scored just one goal in the Premier League this term, but Pochettino is satisfied with his leading striker.
"I am very happy with his performances," the Spurs boss added.
"It's difficult when the striker doesn't score, but we have full confidence in him."
Togo striker Adebayor and Algeria midfielder Nabil Bentaleb are still to return from international duty for assessment, but Pochettino has fitness concerns over a number of other players.
Goalkeeper Hugo Lloris (thigh) and midfielder Nacer Chadli (hip) missed matches for France and Belgium, respectively, during the international break and late decisions will be made on their participation at City.
"Hugo arrived yesterday and was good, but we need to analyse and do tests," Pochettino added.
"We have another day to decide
We need all players to be fit."
United States right-back DeAndre Yedlin, who agreed to move to White Hart Lane from Seattle Sounders in the summer, could move to London in January, depending on Kyle Walker's recovery from an abdominal injury.
"We need to know how Walker is recovering to decide (on Yedlin)," Pochettino added.
"One option is maybe in January (to) bring him here."
