Italy U21 coach Gigi Di Biagio expected more from his players after their 4-1 win Slovakia.
It was a debut win for the former Juventus midfielder.
"The result might seem impressive, but I am not very happy with how we played," Di Biagio told RAI Sport.
"We need to improve a great deal and become more fluid in our style of play, not to mention more determined.
"I knew we could run into difficulties. It is the debut for me and many of the players, but we must always look at the football rather than the result."
