Totti struck both goals for Roma.
Ex-teammate Montella said: "Totti had a fantastic game tonight and it is a pleasure to watch him play. We have had a good season, lately a little less impressive because motivation dropped, but we were inspired by an important adversary and stadium today.
"We always try to play our game and I liked our attitude more after going behind, as we pushed and were almost a little arrogant. Roma played with attacking full-backs and we could've done better on the counter."
