Kaka's opener was pegged back by Michele Ciani.
“It’s a bad moment, as at the first distraction we concede. The team played an excellent first half, not allowing Lazio any opportunities,” he told Sky Sport Italia.
“After going 1-0 up we didn’t take some more chances, but then with this goal we were caught out after a corner and punished.
“The side played well in terms of technique and defending, but we lost our unity a little after the equaliser and allowed a couple of dangerous counter-attacks.
“We have to keep working and putting in this sort of performance. The defence worked very well, which was not easy against Miroslav Klose and Sergio Floccari. Once again, the only mistake we make in a match leads to a goal."
