With off-field issues constantly plaguing the side, Chelsea will be keen to put their on-field form back on course when they host West Brom in their English Premier League game.
The Blues are currently two points behind Tottenham, and a further two separates them from fifth-placed Arsenal, who play Spurs Sunday. Therefore, a win against West Brom is vital to remain on course for a top-four finish.
"I have confidence we can win, the team was training really well, as they have since I've been here, so I'm really pleased with the reaction in terms of training sessions," Benitez said.
"I was really pleased with the performance against Middlesbrough after changing eight players, that means I know what to do. I'm positive we can carry on and finish in the top three or top two, we will see, but that's my feeling.
"Realistically it's not easy, Manchester City are a good team with good players. If they keep winning games it will be difficult, but you never know in football. Top two, top three and two trophies, it's very clear we have good chances.
"It (the north London derby) could change things in terms of the perception, but it will go until the end. If you win you are far away but if you lose and the other team win it changes. We have to carry on until the end with confidence because we have a strong team.
"We will try to do our best in every competition. West Brom are first, then we will try to progress in the Europa league and FA Cup."
Chelsea have been boosted by the return of Gary Cahill and Cesar Azplicueta, who missed the game in midweek, but Yossi Benayoun is ruled out along with long-term absentee Oriol Romeu.
West Brom have problems up front, with Romelu Lukaku ineligible to play against his parent club and Shane Long a major doubt through injury. Goran Popov will also miss out as he serves the last of his three-match suspension.
