The Azzurri defeated Milan 2-1 at the San Siro.
"We worked together as a team tonight and that was very important, as if you have that then the quality players get the chance to shine," said Benitez.
"I like the way my team are playing. I'll say we are now at 73 per cent, but we can still improve these little things and when we do it'll be easier to win.
"The important thing was to show this character right to the end. It wasn't our best performance of the season, but to come here and win for a fifth consecutive victory is impressive."
