AC Milan boss Massimiliano Allegri was delighted with victory over Inter Milan. Milan won the Derby della Madonnina thanks to a Zlatan Ibrahimovic penalty.
Allegri feels he has struck the right balance with Milan, but won't rule out further changes.
"It was a very intense performance and we got off to a great start, putting Inter under pressure," he said of the 1-0 win that maintained their leadership.
"We kept that up while we had XI men on the field, then defended well and it was a deserved victory.
"There was a moment when we looked ready to score the second, but then we started slowing the tempo and fatigue had set in. I liked the attitude and good football, above all the team was solid.
"It's an important victory, especially as a derby win can only help improve self-esteem."
