"I think this change in attitude is huge," he told Chelsea's website. "It is bigger than everyone imagines. You enter the field with it in the back of your mind that today we are not going to lose, or you enter and you say I am going to win today. And we have to work on that.
"This has to go step-by-step. You cannot go for a miracle change, it is impossible. We are a big football club and we need results along the way and you have to do it step-by-step."
"I think you can play a certain way of football that is very similar to Barcelona but you need the players for that - and Chelsea doesn't have (Andres) Iniesta, doesn't have Deco, doesn't have Xavi which are players with a certain quality," he added.
"But Chelsea on the other hand has (Michael) Essien and (Claude) Makelele and (Frank) Lampard - different players with different styles.
"But I think it is not the style of Barcelona players, it is the way they play that is attractive - and with Chelsea with all the players we have and all the quality we have, we can play attractive football that is fun to watch, with the intention of winning the game, not with the intention of not losing the game."
