Zeman axed Daniele De Rossi, Pablo Osvaldo and Nicolas Burdisso from his line-up for the 2-0 win.
He explained: “We were frightened after the Juventus defeat, so to begin with we were stretched out and left too many spaces. If we don’t get courage from the back by going up to help the midfielders, then they tend to pull back instead.
“I have always said that everyone can play in my team and I chose these 11 players to start. I am interested in what the lads do at this moment and right now I considered this to be the best line-up.
“I do not doubt the quality of De Rossi, Osvaldo and Burdisso, as they are important players who I hope can give us a great deal.”
Zeman did explain on Saturday that Burdisso did not understand his tactics yet.
“I spoke about Burdisso, but the truth is I would love 20 players with his mentality and work ethic. Right now he cannot give his best, but he has the right attitude.”
