Leicester are 11th in the league this season and have lost four of their 10 games - more than they lost in the whole of last season.
His equaliser at Tottenham Hotspur at the weekend earned Leicester their first away point of the season and the former Kano Pillars star said he believes the spirit that drove "The Foxes" to an unlikely Premier League conquest is steadily coming back.
Tonight they can seal progress to the knockout stage of the Champions League with victory over Copenhagen. In the Champions League, they're W2-D1-L1 in their handful of matches since 2013/14, with Real Madrid the only side to beat them as they managed a draw against Juventus and beat Galatasaray.
Leicester City's only previous away game in the Champions League was a 3 - 0 win against Club Brugge.
But, however cool, Ranieri has warned his side - who have a 100 per cent record in Europe this season and are yet to concede a goal - they can not take qualification for granted at Parken on Wednesday.
Ranieri was referring to Vardy's assist for Ahmed Musa to equalise against Tottenham last Saturday, and the cross which was knocked down by Islam Slimani for Riyad Mahrez's victor against Copenhagen two weeks ago.
Schmeichel, who won't need any introducing to the crowd given he's followed in the footsteps of dad Peter to become Denmark's No.1 keeper, added: "It's going to be great and I'm really looking forward to it". "I put a big bag of chocolates at the door, people came - unbelievable", the Leicester manager said, laughing. "I think it will be a very good battle tomorrow".
But Ranieri warned: "I understand everybody wants to win but for us it's important to have everything in our hands". "They used Jamie Vardy a lot".
"We can write a new chapter of Leicester's story", said 65-year-old Ranieri. "I don't want to risk Slimani, the physio told me he is OK but "be careful", so why lose a player for one match?"
