The Blues head to the Bernabeu for the first-leg of their Champions League round 16 tie just 12 days after being hit with a two-year ban from European football for alleged breaches of the European governing body's financial fair play rules.
“Why we should we change what happened personally about the behaviour and the determination of our team?" he said. “The last eight competitions we've played, we've won seven, more than determination did this.
“We don't need these kind of things (the Uefa ban) to show what we want - the desire is in every single game we play.
“Sometimes we drop points - this season I think a little bit for the consequences to win a lot of titles, but the desire is absolutely always there. I don't think they are going to do something special because they have this on themselves."
He said that beating Leicester would be a big step towards securing second place in the league, but that it could also have a knock-on effect for Madrid.
“If we play good we are more confident to go to Madrid to play but I'm not going to play this game thinking of Madrid," he said. “Winning games helps to win the next one, that is normal. It is better to go Madrid with a good performance, this performance would help us to win the game.
“But in the end, it will be a different competition. 180 minutes, it will be a different approach to what we have to do."
