The Foxes could seal a top four place if West Ham drop points against Arsenal on Saturday and they then win at Sunderland and Manchester United lose at Tottenham on Sunday
Ranieri has consistently refused to talk about winning the Barclays Premier League title and only entertained reaching the Champions League last month - despite currently being seven points clear at the top
Victory on Sunday will open up a 10-point gap to second placed Spurs if they lose to United but Ranieri insisted he is not thinking about the Champions League yet
He said: "What we do is important, before thinking about everything, then we can check the table
I'll repeat to my players it's important what we do.
"I can wait, the others can win all their matches
I must be focused
I expect Tottenham, Arsenal, everyone to win all their games and then I want to fight to achieve the Champions League
It will be a fantastic achievement.
"At this moment I don't think behind me, I look forward and to the next match
Sunderland is a very difficult match
"I am very happy we saved the team (from relegation), that is important
Our fans continue to dream, a lot of children come to our training ground, it is fantastic.
"Everyone is looking at what happens in the last six matches, me too, I am very curious, but we have to wait
There are a lot of people pushing behind us and that's important but it's important to keep our feet on the ground."
Ranieri won the manager of the month prize for March after three wins and a draw but is taking nothing for granted at the Stadium of Light, with Sunderland four points from safety.
He added: "Sunderland are desperate and it will be a big battle
Sometimes there is pretty football but I am waiting for a battle."
Jeff Schlupp is available after a knee injury while Ranieri has no fresh injury worries.
