His side have the chance to move top of the Barclays Premier League with a win away to current leaders Arsenal on Wednesday night.
City cut the gap to three points at the weekend with a victory over Aston Villa and the boss said that their unity has remained the same through good and difficult times this season.

“Listen, after [beating] Arsenal [in the FA Cup] there wasn’t suddenly this togetherness,” Guardiola said in his pre-match press conference.
“Always I handle incredible human beings and incredible football players since I’ve been here. I don’t complain once.
“Everyone makes mistakes - I’m the first, everyone has their own personalities and try to live together.

“More or less these years we have been perfectly together, players, club, staff, backroom staff. The mood is really good and has been for many years.
“ During the seasons after I said many things happened in the past, success, and many things, sometimes little things must be adjusted, I first have to understand the situation differently.
“We’re delighted to be together, not because we beat Aston Villa and not because we lost to Spurs.”
Victory over the Gunners would see City go back to the top of the table although Mikel Arteta’s side will have a game in hand.
However, with another clash between the two sides to come at the Etihad Stadium in April, the chances of a third title would stay in City’s hands.
But Guardiola says there is still long way to go in the season and that a win would not give a psychological edge.
“Of course it’s important because we can take the points and the best team so far they can’t,” he added.
“But after we have to go to Nottingham Forest and the Champions League and we have the next six fixtures away.
“I have the feeling that many things can happen. So the FA Cup and Champions League is knockout and then we try to arrive in final eight to 10 Premier League games being there.
“This is the deal, the target and tomorrow will help us to be there in the last eight to 10 games.
“There are many tough games away and home for all the contenders.
“Of course, we can’t deny it’s so important for us. If we handle all the aspects these type of games give to you, it’s a big difference.”
