"We can go to Rome and quite comfortably look for the win. Lazio are a great squad and we rested several players, but those who went out there today did very well.
"We struggled a little at the start because some of them hadn't played in a while. Francesco Bolzoni put in a good performance."
The scoreless result leaves everything wide open for the second leg and Lazio boss Delio Rossi felt his men deserved more.
"We tried to win it and had some very good scoring opportunities in the first half, but were unable to convert them.
"We are aware that this is an excellent squad that plays a certain type of attacking football. We proved that again tonight and I am happy for the lads."
