Foden, who scored in Saturday's 1-0 win over Tottenham Hotspur, said this campaign was a much better challenge compared to last season when they won the title by a massive 19 points.
"If we can do this, then people are going to have to start thinking that we're one of the best teams ever," Foden told reporters. "I couldn't be in a better team.
"Every player wants to fight for the team and we're unstoppable with that attitude. When we won the league last time we were miles in front but this is better because we've actually had a challenge, someone fighting with us."
City face arch-rivals Manchester United, who are unbeaten at home in their last 14 league matches, at Old Trafford on Wednesday.
"It's a very difficult game to go to United and play well, but I know we're capable of doing it," Foden said. "And if we win that one we're a step closer. It's all down to us, win all our games (and) we win the league."
However, the 18-year-old, who has started only two league games this season, may have to settle for a place on the bench with the experienced David Silva in line to return.
"Obviously, any game I'm going to play I'm going to be excited," Foden added. "I'm just waiting for my opportunities."
