“It was a different game to Chievo, but above all at the start we were a little hasty. The danger today was to get swept up in the enthusiasm of the stadium for Cristiano Ronaldo's first at the Stadium and we should've had more patience," Allegri told Sky Sport Italia.
“Without Dybala, it becomes more difficult to pass between the lines, but after a while we defended well and did far better in the second half.
“I'm happy with the performance, it was our first head-to-head with one of the other big clubs and it went well.
“At times we fall asleep, at others we get frenetic, whereas we need more balance throughout. The spaces did open up after a while and we should've accelerated when the opponents were more fatigued.
“Once again, the substitutions were very important with Douglas Costa, Emre Can and Rodrigo Bentancur making an impact off the bench.
“We have to improve our tempo, our control and the way we read the game, but the centre-backs did a good job against Lazio's dangerous counter-attacks.
“It's one game per week in the first three rounds, but from September 15 onwards there will be midweek Champions League games too and naturally we'll need everyone. The important thing is that those who come off the bench contribute in the right way."
