The Portuguese defender has been in superb form since returning to the starting XI after the World Cup.
He says the team mentality will be that of a playing in a final as City chase three major trophies in the weeks that remain.
“I think we have been on form in the right time for a long time now,” said Dias.
“It is that time of year and every game you are either in or out with Champions League elimination rounds and also the way it goes in the Premier League.
“We have been fighting finals for a long time now and it will keep being the same until the end.
“It comes from ambition - ambition for us all. Ambition is one of our best characteristics.
“We are all very ambitious and when this time comes, no one hides - everyone shows up and does their best to be there for the team.”
Dias says eliminating Bayern Munich 4-1 in aggregate in the Champions League quarter-finals was a confidence booster - even for a team already brimming with positivity.
“If you play well, you keep winning and you keep performing, especially when you face Bayern Munich and you are able to beat them, I think for the team, for everyone, it is a big boost for the confidence,” he said.
“It definitely helps you accumulate that good energy. But in the end, you always need to remember that the challenge is gone, it’s done, it’s been great, but you have another one in just three days.
“That is the biggest challenge. Also, throughout the season as it is the life that we live, but especially in this moment as it is all finals.”
Looking ahead to Wednesday evening’s summit clash with Arsenal, Dias says the game is a title decider – but just as each of our final Premier League games will be.
“I guess it is a title decider, as will the next one against Fulham and the one after that against West Ham and so on,” he said.
“It is just another part of the title race. It is definitely a big one because we are playing against our main opponent, and it is a good time to make a statement.
“But we know that after this game, there is still a long way to go and many games to be played. Our total focus is on tomorrow’s game, but knowing there is still a long way to go.
“We all know how good Arsenal are and what they are capable of. But we also know how difficult it is in this part of the season.
“It is all seems fantastic and great, but it is not done until it is actually done.
“It is in these moments that you really need to push instead of just trying to maintain. You need to push and go for all of it. It is not really how it begins or in the middle, it is how it ends.
“For us, I think the most important is the mix between having that experience and everyone still being so hungry.
“Everyone needs and wants more. No one is satisfied and especially when you get to this part and you are in the competitions, the appetite just comes.
“The fact that no one has lost that appetite is what keeps us coming back again. To be here again is a privilege for us all.
“We have obviously been here before and we know what we have to do. We will try to do it again.
“To make things happen, you need to visualise them first.
“But then, right after that you need to remember that you need to think about today and not think too far ahead as you will lose the focus and the possibility of fighting for something great.”
