Ibrahimovic, who scored with a second half header, was clearly pleased with the result at Rome's Stadio Olimpico.
Speaking on the Inter Channel he said: “In other games I had more chances and didn’t score, but what makes me really happy is the performance of the team.
“It is never easy to win away to Lazio, but we all did very well and played the way we wanted to. We went on to the field with character, strength and quality.
“Now we must continue like this, right the way to Christmas. Physically I feel great and want to play all the time.”
