Miroslav Klose scored the only goal of the game after the Nerazzurri had already hit the upright twice.
"Lazio were the better team in the first half, as we were never able to threaten, even though we didn't concede any real scoring opportunities either," the Coach told Sky Sport Italia.
"After the break we put in a great performance. Inter deserved to take the lead, but incidents went against us and Klose is a champion. That's football, we didn't deserve to lose.
"We were missing something in the first half and a lot of that was down to the way Lazio played, but we showed that we were a great team.
"We were unlucky with incidents and a few decisions that went against us. We are not stronger than the incidents, that is all I'll say."
